What you need for IITJEE ….
It is a common belief that preparation for IIT- JEE is all about solving difficult problems and those who succeed in clearing fit are really genius. This is not completely true. What makes some of the problems look appear difficult is the deep concepts and more often a mix of concepts involved therein. Barring a few top ranking students, others get success by consistent hard work, focused approach, efficient time management and a high motivational level.

In fact, from the realistic point of view, an IIT-JEE level competitive examination doesn't provide any space or permit any scope for those having superficial knowledge rather calls for the significance of having both extensive and intensive knowledge about the subjects being tested in the examination. Experts in the field, have it that it is the extensive study during the initial stages of the preparation, to be supplemented by the regular dopes of/practicing as many numerical problems as possible can be a contributory factor for one's ultimate success in the examination. Because it is here, where an aspirant's extensive study in the subject would be put to an acid test. If he / she manages to solve such numerical problems with much ease, yet maintaining accuracy and speed in equal measure, he/she shall be deemed to have gained that essentially required hold and grasp in the subject so, as to substantially increase one's chances of finally cracking it.

However, on the same scale, the experts in the field do recommend that the tempo of preparation must be substituted to intensive study exercises specially, towards the approaching date of 'D-day, for the same would facilitate an aspirant to brush up the vital topics and collective knowledge having been acquired through the initial stages of preparation by virtue of extensive study exercises.

However, about the credentials of our coaching being nothing less than the best; at GTIM it's our constant endeavour to expose you to both extensive and intensive study regimes so as to make you adoptive to the level of inputs required to be put into and acclimatize yourself to the rigorous study exercises vital to take the IIT-JEE head on and succeed in the competitive scramble.

While owing to our expertise & experience in this specialized field of coaching, we are confident that our rigorous coaching regime batted fey a regular system of evaluation, shall go a long way to prove our distinctiveness vis-a-vis our competitors.

Strategy for IITJEE – AIEEE

Strengthening fundamentals:
Most of the questions are based on fundamentals & their applications. So, the first step is to establish a solid base by mastering the fundamentals. For mastering the fundamentals you have to be focused. Don’t refer too many books.

When you start a new chapter, the learning curve is slow that you do not accomplish similar amount of learning every day even though you spend same amount of time everyday. So even if your learning process is slow, keep studying day after day without getting discouraged. All the subjects are equally important. Devote more time to subject/topic you are weak in (remember most of us tend to devote more time on areas we are strong & often shy away from our weakness). In most of the examinations minimum qualifying marks are there for each subject. Hence make sure that you do not ignore any subject & allocate adequate time to each subject.

Strengthening Application of fundamentals
Quality is more important than Quantity: Doing 100 quality & concepts based questions is more important than doing 1000 questions which have not been selected carefully. Remember that the purpose is to sharpen problem-solving skills. Start with conventional methods of problem solving but improvise constantly & build you own shortcuts & ways of attacking a problem.

While practicing the problem always try to solve the problem on your own. If you are unable to solve a problem do not hurry to consult the solution. Study the relevant theory again, paying attention to the finer points and the problem in the back of mind.

Experience shows that studying the theory with a definite problem in mind is very effective and also sharpens the problem solving skills. Remember that directly going though the solutions is not going to help you at all. The key in problem solving does not lie in understanding the solution to the problem but to find out what clues in the problem leads you to the right explanation. In case you are not able to solve the problem try to find out the reason by analyzing the level of problem & practice similar kind of problems so that you can master the tricks involved.

While doing problem solving try to strengthen and develop your conceptual understanding by analyzing deeply and correlating the problem with real life situations. While practicing identify your strong & weak areas (subject wise/topic wise/question wise). Testing your preparation chapter by chapter can do this. Through a structured test you should be able to diagnose which chapter, which concept & what type of problems you need to practice more.

Strengthening Speed /Strike rate & Examination temperament
Always keep track of your average speed of solving questions.
It has been observed that most of the students loose 15 to 20% of their marks not because they do not know the subject but because they fail to apply the basic concepts correctly. This is basically due to examination fear & pressure. These marks that a student looses because of silly mistakes (calculation errors, confusion, fail to apply the right concepts, solving the problem by long method) can be reduced if a student regularly participates in test series based on the pattern & level of final exams.

Speed: Speed building comes through the following:
Memorizing land mark problems (remembering standard formulae, concepts so that you can apply them directly) Being strong in mental calculations (never use the calculator during your entire preparation, try to do first and second level of calculations mentally, remember as vocalization reduces reading speed, similarly doing calculation on paper reduces the speed. Working with choices (see all the options and do not go for last digit accuracy unless required by the problem) when you are doing subject wise exercises you can also calculate speed subject wise.

Here we would like to highlight one more point that just good speed is not enough because of negative marks, so a high speed with less accuracy may be harmful.

Strike Rate: This originates the second important factor, the strike rate. Strike rate means the percentage of correctly attempted questions

Strike rate can be improved with the help of intelligent guessing. Intelligent guessing means guessing a question you are not completely sure but have some idea about. Your objective is not to solve the question but choosing the correct option out of the 4 given choices. So always try to eliminate the choices. Remember that if one choice is eliminated, chances of your guess being right is 33% (in comparison to a blind guess where the chances of being right is 25%) and if two are eliminated the chances of hitting the right answer are 50 %

So remember that a good speed or strike rate alone cannot give you success. One without the other is a good way to mess up a potentially good performance. So, what is required is a good combination of both speed and strike rate.

Also remember that cut-off in most of the exams moves between 60 to 70%. So if you focus on easy and average question i.e. 85% of the questions, you can easily score 70% marks without even going to difficult question. Try to ensure that in the initial 2 hours of the paper the focus should be clearly on easy and average question, after two hours you can decide whether you want to move to difficult questions or revise the ones attempted to ensure a high strike rate. Always keep in mind that normally questions in any competitive exams can be categorized into 3 areas

Easy: Approximately 25% questions in a paper are easy
Average: Approximately 60% questions in a paper are average
Difficult: Approximately 15% questions in a paper are difficult

The easy and average questions ensure selection whereas the difficult questions make the merit. You should focus on careful selection of the easy and average questions and avoid difficult questions in the first and second round and come back to them once you have completed the entire paper once.

Our study material based on our experience with the students over past many years has taken a shape of books which have been published by CENGAGE LEARNING (earlier known as “THOMSON PUBLICATION”). This books are now top selling books in India.

What is Engineer?
Anybody can come up with a good idea for a faster car, more powerful computer, or taller building, but if you want to make it happen, you are going to need an engineer. Engineers are the people who turn dreams into reality. Yet many people are not really sure what engineers do. That’s why engineering is often though of as the “invisible profession.” Yet everyone does a little engineering in his or her life. Have you ever built something out of Legos or blocks? That’s a form of engineering, and you probably didn’t even know it. Engineers created the roadways we use to travel across our country, build spaceships to explore outer space, design submersible craft to explore the ocean floor, and even create systems to carry water from the mountains to our kitchen sinks. Just about everything we own needed an engineer to design and build it. Engineers even create the tools we use to build things and the materials we use to build things with. Engineers use math and science to create something of value from our natural resources. Yet engineering is not really considered science. Most engineers generally don't "do" science. Science is about discovering the natural. Engineering is creating the artificial. "Scientists discover the world that exists; engineers create the world that never was." Engineers are very creative people. They synthesize, solve problems, and innovate. Engineers are always looking for ways to do things better. To an engineer there is no such thing as the fastest or most powerful.

Engineers apply the principles of science and mathematics to develop economical solutions to technical problems. Their work is the link between perceived social needs and commercial applications.

Engineers consider many factors when developing a new product. For example, in developing an industrial robot, engineers precisely specify the functional requirements; design and test the robot’s components; integrate the components to produce the final design; and evaluate the design’s overall effectiveness, cost, reliability, and safety. This process applies to the development of many different products, such as chemicals, computers, gas turbines, helicopters, and toys. In addition to design and development, many engineers work in testing, production, or maintenance. These engineers supervise production in factories, determine the causes of component failure, and test manufactured products to maintain quality. They also estimate the time and cost to complete projects. Some move into engineering management or into sales. In sales, an engineering background enables them to discuss technical aspects and assist in product planning, installation, and use. Supervisory engineers are responsible for major components or entire projects.

Engineers use computers extensively to produce and analyze designs; to simulate and test how a machine, structure, or system operates; and to generate specifications for parts. Many engineers also use computers to monitor product quality and control process efficiency. The field of nanotechnology, which involves the creation of high-performance materials and components by integrating atoms and molecules, also is introducing entirely new principles to the design process.

Mechanical Engineering

Mechanical means mechanisms of machines. A Mechanical engineer is a person skilled in design, Production and Maintenance or repair of machines. It is a discipline in which mathematics and science are blended with experience and judgment for the production of useful serviceable goods with economy of the material.

Mechanical engineers study the behavior of solids, liquids and gases when forces are applied to them and when they are heated and cooled. They learn how to convert energy efficiently from one form to another. Using these knowledge bases, mechanical engineers play key roles in the design of transportation systems, including automobiles and space vehicles; environmental control systems, including air conditioners and furnaces; manufacturing machinery and processes, including robots; energy conversion technology, including engines and power plants; biomedical devices; and the list goes on. This tremendous breadth in the scope of the mechanical engineering profession gives the mechanical engineer access to employment in every major industry imaginable. Mechanical engineering faculty are highly acclaimed and research areas as diverse as combustion mechanics, the movement of aerosols, rotocrafts, biomedical and aerospace engineering.

Mechanical engineers research, develop, design, manufacture, and test tools, engines, machines, and other mechanical devices. They work on power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines, as well as power-using machines such as refrigeration and air-conditioning equipment, machine tools, material handling systems, elevators and escalators, industrial production equipment, and robots used in manufacturing. Mechanical engineers also design tools that other engineers need for their work. Mechanical engineering is one of the broadest engineering disciplines. Mechanical engineers may work in production operations in manufacturing or agriculture, maintenance, or technical sales; many are administrators or managers.

Apart from campus recruitments the Mechanical Engineering graduates find their jobs in merchant navy, and the three wings of Armed forces. With the growing automation, Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) have opened up lucrative job position in software engineering for Mechanical Engineers.

Electrical Engineering

Electrical design devices and systems involving software and hardware that meet human needs. Some are very large, such as power generating systems in dams, others are tiny, such as the microcircuits used in computer systems. Electrical engineers are involved in all facets of the process: manufacturing, marketing, installing, maintaining and designing these systems.

Electrical engineers design, develop, test, and supervise the manufacture of electrical equipment. Some of this equipment includes electric motors; machinery controls, lighting, and wiring in buildings; automobiles; aircraft; radar and navigation systems; and power-generating, -controlling, and transmission devices used by electric utilities. Although the terms “electrical” and “electronics” engineering often are used interchangeably in academia and industry, electrical engineers have traditionally focused on the generation and supply of power, whereas electronics engineers have worked on applications of electricity to control systems or signal processing. Electrical engineers specialize in areas such as power systems engineering or electrical equipment manufacturing.

Electrical engineers work with electricity in its many forms - from the electrons to the large scale magnetic fields. In addition to designing new products, they construct, operate, and maintain a wide variety of electrical systems and equipment. Some specialize in electronics, others in even more specific areas, like space communications or industrial robotics.

There are numerous specialties that can be developed from a degree in electrical engineering. Some of the areas of specialty that can evolve from electrical engineering are: design and application of computer systems; electron magnetic fields; communication theory and signal processing; electrical integrated circuits, and electron devices; energy and power control systems.

Civil Engineering

Seeing the changing skyline, the heaps of bricks and cement, and pages and pages of real estate information, you know this is a country in the throes of change. Everyday we read about new townships coming up, the Metro rail extending its network, booming infrastructure development (roads, airports, bridges etc.) and development preparations for the Commonwealth Games in 2010. If there is one career common to all this feverish activity, it is that of civil engineers.

Civil engineers design, plan and execute the construction work for any structure. They are involved in the planning, research, survey and construction of all kinds of buildings, whether it is a house, factory, stadium or airport, as also roads, traffic and transportation systems, irrigation and power plants, water supply and sewage disposal plants, ports and harbours, oil rigs, water distribution system, wastewater collection system design, dam design, foundation design for every equipment in industry etc, Civil engineers are mainly responsible for planning and designing a project and having it constructed to the required scale.

Civil engineers can work at a construction site or as consultants. While the work itself is basically the same, site engineers take responsibility for the actual construction work. The work involves interpreting the architects’ designs, devising an overall plan for the construction of the proposed project, working out the cost of the construction, supervising the feasibility studies, making site investigations and advising clients on materials and contractors for the actual construction. Civil engineers also take responsibility for the accuracy of drawings and quantities of materials required for the project, supervise the work schedule and conduct periodic checks.

Chemical Engineering

Chemical engineers apply the principles of chemistry to solve problems involving the production or use of chemicals and biochemicals. They design equipment and processes for large-scale chemical manufacturing, plant and test methods of manufacturing products and treating byproducts, and supervise production. Chemical engineers also work in a variety of manufacturing industries other than chemical manufacturing, such as those producing energy, electronics, food, clothing, and paper. They also work in healthcare, biotechnology, and business services. Chemical engineers apply principles of chemistry, physics, mathematics, and mechanical and electrical engineering. Some may specialize in a particular chemical process, such as oxidation or polymerization. Others specialize in a particular field, such as materials science, or in the development of specific products. They must be aware of all aspects of chemicals manufacturing and how the manufacturing process affects the environment and the safety of workers and consumers.

Chemical Engineers make decisions concerning:
» Which reaction pathway should be used to make the product?
» How to purify the desired product?
» How to control the process and ensure it is safe?
» How to make the process cost effective?
» What should be done with any by-products formed?
» How to reduce the amounts of unwanted by-products formed?
» What to do with unreacted raw materials?
» How to recycle energy within the process?

Computer Engineering

Electrical and Computer Engineers adapt engineering principles and science to make useful products. Whether its voice, video, or data transmission, over copper wires, fibre optics or microwave networks, engineers design the systems that make them run.

Computer engineers are involved in the design, implementation and testing of modern computer processors such as the Pentium and PowerPC, as well as designing and implementing the software that runs on these. Computer engineers are also involved in the design and use of artificial intelligence and digital design in engineering.

Computer engineering (also sometimes called Computer systems engineering) is a specialised discipline that combines electrical engineering and computer science. A little-known subdivision is the study of computer engineering technology, which studies the techniques and applications of computer engineering with less emphasis on the mathematical and scientific theory. ...Computer hardware engineers research, design, develop, test, and oversee the installation of computer hardware and supervise its manufacture and installation. Hardware refers to computer chips, circuit boards, computer systems, and related equipment such as keyboards, modems, and printers. Computer software engineers — often simply called computer engineers—design and develop the software systems that control computers. The work of computer hardware engineers is very similar to that of electronics engineers, but, unlike electronics engineers, computer hardware engineers work exclusively with computers and computer-related equipment. The rapid advances in computer technology are largely a result of the research, development, and design efforts of computer hardware engineers.

The world is in the midst of a technological revolution that is being fueled by continuous improvements in the speed and capabilities of computers. Computer engineers are concerned with the design, development, and implementation of new and challenging computer technology in a myriad of consumer, industrial, commercial, and military applications. For example, every major automotive subsystem (engine, traction, brakes, suspension, climate control, instrument cluster, etc.), on a modern automobile is computer controlled. Working in these areas requires expertise in all aspects of computer hardware and software, and requires the engineer to be able to make hardware/software tradeoffs in developing an optimum system design.

Rather than just using a computers, computer engineers apply scientific theory and engineering design to use and develop new computer hardware or software. They write programs to solve problems and create more efficient ways of doing things. They also design new systems and machines, like robots, that rely on computers to operate.

Electronics Engineering

Electronics engineers, except computer, are responsible for a wide range of technologies, from portable music players to the global positioning system (GPS), which can continuously provide the location of a vehicle. Electronics engineers design, develop, test, and supervise the manufacture of electronic equipment such as broadcast and communications systems. Many electronics engineers also work in areas closely related to computers. However, engineers whose work is related exclusively to computer hardware are considered computer hardware engineers. Electronics engineers specialize in areas such as communications, signal processing, and control systems or have a specialty within one of these areas—industrial robot control systems or aviation electronics.

Petroleum Engineering

It is specialize branch of Chemical Engineering. Petroleum engineers search the world for reservoirs containing oil or natural gas. Once these resources are discovered, petroleum engineers work with geologists and other specialists to understand the geologic formation and properties of the rock containing the reservoir, determine the drilling methods to be used, and monitor drilling and production operations. They design equipment and processes to achieve the maximum profitable recovery of oil and gas. Because only a small proportion of oil and gas in a reservoir flows out under natural forces, petroleum engineers develop and use various enhanced recovery methods. These include injecting water, chemicals, gases, or steam into an oil reservoir to force out more of the oil and doing computer-controlled drilling or fracturing to connect a larger area of a reservoir to a single well. Because even the best techniques in use today recover only a portion of the oil and gas in a reservoir, petroleum engineers research and develop technology and methods to increase recovery and lower the cost of drilling and production operations.

One of the factor that affects the economy of country is import of petrol and oil pool deficit. Earlier only government public sectors like ONGC and GAIL were involved in oil exploration. But now private sector participation like Reliance, ESSAR oil have given boost to this sector which will help India to cut its oil pool deficit. Also many Indian companies have expertise in oil exploration and they are working in different counties. So there is tremendous scope in this industry now and in future.

Industrial Engineering

Industrial engineers determine the most effective ways to use the basic factors of production—people, machines, materials, information, and energy—to make a product or to provide a service. They are mostly concerned with increasing productivity through the management of people, methods of business organization, and technology. To solve organizational, production, and related problems efficiently, industrial engineers carefully study the product requirements, use mathematical methods to meet those requirements, and design manufacturing and information systems. They develop management control systems to aid in financial planning and cost analysis, and design production planning and control systems to coordinate activities and ensure product quality. They also design or improve systems for the physical distribution of goods and services, as well as determine the most efficient plant locations. Industrial engineers develop wage and salary administration systems and job evaluation programs. Many industrial engineers move into management positions because the work is closely related to the work of managers.

Aerospace Engineering

Aerospace engineers design, develop, and test aircraft, spacecraft, and missiles and supervise the manufacture of these products. Those who work with aircraft are called aeronautical engineers, and those working specifically with spacecraft are astronautical engineers. Aerospace engineers develop new technologies for use in aviation, defense systems, and space exploration, often specializing in areas such as structural design, guidance, navigation and control, instrumentation and communication, or production methods. They also may specialize in a particular type of aerospace product, such as commercial aircraft, military fighter jets, helicopters, spacecraft, or missiles and rockets, and may become experts in aerodynamics, thermodynamics, celestial mechanics, propulsion, acoustics, or guidance and control systems.

Materials Engineering

Materials engineers are involved in the development, processing, and testing of the materials used to create a range of products, from computer chips and television screens to golf clubs and snow skis. They work with metals, ceramics, plastics, semiconductors, and composites to create new materials that meet certain mechanical, electrical, and chemical requirements. They also are involved in selecting materials for new applications. Materials engineers have developed the ability to create and then study materials at an atomic level, using advanced processes to replicate the characteristics of materials and their components with computers. Most materials engineers specialize in a particular material. For example, metallurgical engineers specialize in metals such as steel, and ceramic engineers develop ceramic materials and the processes for making ceramic materials into useful products such as glassware or fiber optic communication lines.

Mining and Geological Engineering

Mining and geological engineers, including mining safety engineers, find, extract, and prepare coal, metals, and minerals for use by manufacturing industries and utilities. They design open-pit and underground mines, supervise the construction of mine shafts and tunnels in underground operations, and devise methods for transporting minerals to processing plants. Mining engineers are responsible for the safe, economical, and environmentally sound operation of mines. Some mining engineers work with geologists and metallurgical engineers to locate and appraise new ore deposits. Others develop new mining equipment or direct mineral- processing operations that separate minerals from the dirt, rock, and other materials with which they are mixed. Mining engineers frequently specialize in the mining of one mineral or metal, such as coal or gold. With increased emphasis on protecting the environment, many mining engineers work to solve problems related to land reclamation and water and air pollution. Mining safety engineers use their knowledge of mine design and practices to ensure the safety of workers and to comply with government safety regulations. They inspect walls and roof surfaces, monitor air quality, and examine mining equipment for compliance with safety practices.

Marine Engineering and Naval Architects

Marine engineers and naval architects are involved in the design, construction, and maintenance of ships, boats, and related equipment. They design and supervise the construction of everything from aircraft carriers to submarines, and from sailboats to tankers. Naval architects work on the basic design of ships, including hull form and stability. Marine engineers work on the propulsion, steering, and other systems of ships. Marine engineers and naval architects apply knowledge from a range of fields to the entire design and production process of all water vehicles. Workers who operate or supervise the operation of marine machinery on ships and other vessels also may be called marine engineers or, more frequently, ship engineers.

Nuclear Engineering

Nuclear engineers research and develop the processes, instruments, and systems used to derive benefits from nuclear energy and radiation. They design, develop, monitor, and operate nuclear plants to generate power. They may work on the nuclear fuel cycle—the production, handling, and use of nuclear fuel and the safe disposal of waste produced by the generation of nuclear energy—or on the development of fusion energy. Some specialize in the development of nuclear power sources for spacecraft; others find industrial and medical uses for radioactive materials, as in equipment used to diagnose and treat medical problems.


Biotechnology in one form or another has flourished since prehistoric times. When the first human beings realized that they could plant their own crops and breed their own animals, they learned to use biotechnology. The discovery that fruit juices fermented into wine, or that milk could be converted into cheese or yogurt, or that beer could be made by fermenting solutions of malt and hops began the study of biotechnology. When the first bakers found that they could make a soft, spongy bread rather than a firm, thin cracker, they were acting as fledgling biotechnologists. The first animal breeders, realizing that different physical traits could be either magnified or lost by mating appropriate pairs of animals, engaged in the manipulations of biotechnology.

What then is biotechnology? The term brings to mind many different things. Some think of developing new types of animals. Others dream of almost unlimited sources of human therapeutic drugs. Still others envision the possibility of growing crops that are more nutritious and naturally pest-resistant to feed a rapidly growing world population. This question elicits almost as many first-thought responses as there are people to whom the question can be posed.

In its purest form, the term "biotechnology" refers to the use of living organisms or their products to modify human health and the human environment. Prehistoric biotechnologists did this as they used yeast cells to raise bread dough and to ferment alcoholic beverages, and bacterial cells to make cheeses and yogurts and as they bred their strong, productive animals to make even stronger and more productive offspring.

Throughout human history, we have learned a great deal about the different organisms that our ancestors used so effectively. The marked increase in our understanding of these organisms and their cell products gains us the ability to control the many functions of various cells and organisms. Using the techniques of gene splicing and recombinant DNA technology, we can now actually combine the genetic elements of two or more living cells. Functioning lengths of DNA can be taken from one organism and placed into the cells of another organism. As a result, for example, we can cause bacterial cells to produce human molecules. Cows can produce more milk for the same amount of feed. And we can synthesize therapeutic molecules that have never before existed.
