Top 10 Mistakes to Avoid in IIT-JEE Preparation

Updated On - March 12th 2018

JEE Main 2017 will be held on April 02, 2017 and April 08 & 09, 2017 while JEE Advanced 2017 will be conducted on May 21, 2017. JEE (Joint Entrance Examination) is conducted for admission to UG engineering courses to IITs, NITs, and many other government funded colleges.

JEE Main is conducted in both online and offline mode. The exam consist of 90 questions - 30 each from Physics, Chemistry and Mathematics. The duration of the exam is 3 hours. JEE Main syllabus is based on class 11th and 12th curriculum prescribed by NCERT and CBSE. The top 2,20,000 All India Rank holders in JEE Main will qualify for JEE Advanced. JEE Advanced consists of two papers with each paper containing 3 sections – Physics, Chemistry and Mathematics.

A comprehensive strategy is required to perform well in any entrance exam. There are plenty of things that students need to do while there are others that they must avoid to perform well in JEE Main and JEE Advanced. Thus, one important question is “what mistakes to avoid while preparing for IIT JEE?” Given below are some common mistakes that students usually commit while preparing for IIT-JEE.

Do not be Ignorant About Syllabus

Do not be ignorant about the syllabus. It is important to know the correct topics that you need to focus upon during preparation. Sometimes you spend a lot of time on topics that are not a part of the syllabus or don’t carry much weightage in terms of marks. Know the entire syllabus before hand and focus only on topics that require maximum attention and carry high weightage in the test. Students refer to a lot of books for preparation and in doing so often overlap chapters which are important. Look up the actual syllabus of JEE from the official website and make your preparation time table accordingly.

Do not leave the difficult topics for another time

Every chapter of the syllabus is important but there are a few chapters in each subject that require special attention. These topics often form the basis of other chapters and a good proficiency in these topics can really boost your score. Usually, students leave these topics for the latter and often skip these topics. There is no better time to study than now. Do not procrastinate and miss out essential topics. Please do not skip Inorganic Chemistry in the Chemistry section. The questions asked from this section are very direct and straight-forward. Important topics from each subject are given below.

Physics: In Physics, the laws of motion and laws of conservation (angular momentum, energy, field theory, etc.) should be prepared thoroughly. To prepare well for numericals, students must study Kinematics and Dynamics properly. Electromagnetism, Current electricity, Waves are also very significant topics. These are scoring topics and a number of questions are usually repeated from this topic every year. Modern physics is an important topic for both JEE Main and JEE Advanced 2017. The basics of this topic can be learnt from the NCERT textbooks. Optics is another easy and important topic. Both Modern Physics and Optics are scoring too. So make it a point to study all these topics thoroughly. Practicing problems is the key to success for this subject.

Chemistry: Do not skip topics like States of matter, Chemical bonding and molecular structure, Chemical thermodynamics, Equilibrium, Chemical Kinetics i.e. the Physical chemistry subject from both 11th and 12th are very important. Study Organic Chemistry properly. Students often avoid studying its difficult concepts which can cost them dearly in the exam.

Mathematics: Differentiation, Application of derivatives and Definite Integral i.e. the whole of Calculus is very important. These topics can be also used for calculations in Physics and Chemistry. Some other topics such as 3-D Geometry, Vectors, Trigonometric ratios, Integration and Complex numbers contain some basic topics that should be covered. Co-ordinate geometry, Probability and Statistics, Permutations and Combinations are must reads. Topics like Inverse trigonometric functions, Circles and family of circles and Sequence and series are fundamental topics that students can revise only once. Do not ignore scoring and easy topics like Limit and continuity, Matrices and Determinants and Straight lines and pair of straight lines.

Do not Neglect the Basics

Conceptual clarity is the key to crack any entrance test. The questions asked in JEE are conceptual and application based. If your concepts are not clear, you will not be able to apply them while solving problems. Do not try to find shortcuts to learn concepts. Learn all concepts in depth, and then you can create your own shortcuts and implement them. NCERT textbooks are reliable for understanding preliminary concepts. Solve questions after each chapter as these questions test your understanding of concepts and problem solving ability. The language used is easy and they also have illustrations that help in better understanding of topics.

Do not Study Selectively

Avoid selective studying in all 3 subjects. JEE exam setters often test basic concepts by mixing them up with other concepts. So, you can expect questions in the exam that require application of two or more concepts. Try to incorporate all the important concepts in your plan of study.

Do not Miss Lectures

Do not miss classes in your coaching institutes or schools. These lectures will help you learn and understand in continuity. Missing a single lecture will result in you not understanding what is being taught in the next. Even if you have studied the concept earlier, attend it again considering it to be revision. You might even end up learning something completely new.

Do not jump from book to book

Students have a habit of collecting reference books and hopping from one book to another without completing any of them. This could lead to confusion among candidates. Stick to only some reference books and finish them thoroughly. First refer to the NCERT textbooks for Class 11th and 12th. Most IITians swear by these books as their fundamentals. Consult advanced level books only after you have gone through the basics to avoid confusion. Some good reference books for each subject are mentioned below in the table.

Do not Forget to Revise 11th standard syllabus

 Start revising 11th standard syllabus as soon as you are done with 12th. The topics covered in this grade form the basis of most topics from 12th. Do not forget that almost 40 - 45% questions asked in JEE are from 11th standard. Pay more attention towards chapters from the later-half in class 11th textbook.

Do not Forget Part B of Physics

Students often forget that questions of practical nature are asked in JEE. Part B of Physics can have questions about Vernier callipers, resistance of a given wire, coefficient of viscosity, optical benches, resistance of galvanometer, etc. The syllabus of JEE Main 2017 states that 20% weightage will be given to experimental skills. The problems usually asked are simple and scoring hence it is a good opportunity to maximize your score.

Do not Miss out on Questions with NO Negative Marking

There are a few questions like ‘match the following’ in JEE Advanced that do not have negative marking. Do not leave such questions unattempted. Take a chance; you might get them right by fluke. Read the marking scheme correctly as it will improve your overall score.

Do not be Over- or Under-confident

Revise chapters from time to time otherwise you might end up forgetting them. Don’t underestimate your competition. Note down formulae for every chapter. Solve as many numerical problems as you can within the available time. Maintain a book that has notes about the approach towards a numerical or theory. Thoroughly read the questions and choices before marking your answer. Mark your circle as soon as you get the answer to avoid blunders. Don’t get stuck at one question, move on to the next.

Have a 100% strike rate for questions that you attempt. If you are not confident about a question, do not attempt it. Don’t worry if a section is tough, you can make up for that in the other sections. If the exam paper has questions which have numerical values as its options then discard the highest and lowest value. In more than 50% cases, the highest and lowest values aren’t the correct choices. Solve the problem and choose the option that is closest to your answer.

Good Luck!
