Indian Institute of Technology (IIT) conduct a Joint Entrance Examination (JEE) every year for the admission to its B-Tech and other courses offered at the IIT Mumbai, IIT Kanpur, IIT Delhi, IIT Chennai, IIT Kharakpur, IIT Guwahati, IIT Roorkee, IT Varanasi and ISM Dhanbad.

IIT JEE Exam Pattern:

There are two papers: Paper 1 & Paper 2. Both the papers have three separate sections on Physics, Chemistry & Mathematics. The papers are of objective type and are designed to test comprehension and analytical ability of candidates. Those candidates who clear the JEE and are desirous of joining the B. Arch and B. Des. Courses are required to appear in an Aptitude Test conducted at each counseling Institute. The test is of two hours duration Candidates who fail in the Aptitude Test are not eligible for admission to either B. Arch. or B. Des. Courses.

Mathematics
To score in mathematics, you need to have the ability to solve simple, stereotypical questions, as well as challenging and complex problems that you might have to face unexpectedly.

1. While attempting questions, try not make make any particular problem a prestige issue. Hence, if you are unable to solve the problem within a reasonable amount of time, you should skip the question and move on. Always remember that There may be simpler problems awaiting you

2. Don’t be tempted to guess the answer to a question. It may prove costly if there is negative marking

3. Also, always try and attempt some mock question papers in a simulated environment before the D-day. In fact, there are many online tests that provide useful mock practice tests for students. One such website is

Physics

The format of the physics section in the JEE question paper changes every year. Subjective problems, which involve detailed solutions, have been dispensed with. For the first time, in JEE-2007, questions based on paragraph, assertion-reason type questions and questions on matrix matching were included. In JEE-2008, MCQs with more than one correct choice were included in the paper.

Identification of problem areas

In each chapter, identify the problem areas, which need closer study. Prepare a note of the questions you failed to solve in the first attempt. Write down the correct solutions in a separate notebook. If you are unable to solve a problem, consult your teacher. In physics, checking the given choice for dimensional consistency is often very helpful.

Questions based on experiments

In the physics paper, there is at least one question based on an experiment. You must learn how to determine the least count of measuring instruments such as vernier calipers, micrometer screw and spherometer, and to use them in making measurements.

Chemistry

The three branches of chemistry are evenly represented in both the papers in the JEE. The chemistry paper in the year 2008 was in the following format in both Paper I and Paper II: Straight-objective type: This involves questions with four alternative answers, of which only one is correct.

Multiple-correct answer type: This involves questions with four alternative answers, of which more than one is correct. Reasoning type: Here, each question involves two statements, which have to be correlated with each other. Only one answer is correct. Linked-comprehension type: This is a paragraph stating certain facts, from which a set of three questions is framed with four alternative answers, of which only one is correct.

Physical chemistry

The subject matter in physical chemistry involves topics with well-focused principles. Their application to different problems is straightforward. You should pay more attention to this branch of chemistry so that you can solve problems related to it more comfortably. Be thoroughly prepared with: Bohr’s theory of atomic structure, quantum numbers and orbitals MO approach to diatomic molecules, hybridisation/ VSEPR theory Vander Waals equation of state and application to behaviour of real gases Crystal systems, packing of atoms, ionic solids and density of crystals Colligative properties of non-electrolytic and electrolytic solutions Electrolysis, conductance and galvanic cells Differential and integrated rate laws, effect of catalyst and temperature on the rate of reaction Determination of PH of acids, bases and salt solutions (including hydrolysis) and solubility product Le-Chatelier Principle, relation between Kp and Kc Stability of nuclei Thermo-chemical calculations and criterion of spontaneity
