Subject-Wise Tips You Need To Know For The Best JEE 2021 Preparation

The 2021 JEE attempt is nearing and it’s time you upped your game in starting your final preparations. The JEE Main 2021 will be conducted by NTA in multiple sessions (February/March/April/May 2021) for admissions in the next academic year. With less than a month to go for the first session of JEE Main to be conducted from 23rd to 26th February in two shifts, you need to plan your studies effectively. To ace these exams and get into a great college with that high score, here are a few subject-wise tips you need to gaze through immediately!

So your target is set, and all that you need to do next is find the best possible way to reach it.

Coming to the exams that are to be held in February, the JEE Mains will now be held in a new pattern. The candidates will get a choice to attempt 75 questions out of 90 – or 25 out of 30 questions in each section of Chemistry, Physics, and Mathematics. So, in order to excel at these subjects and raise your scores, here are the tips you need to know!


Mathematics is both- scoring as well as a section that may make or break your final score.

Practice Makes Perfect: Mathematics requires regular practice. You should devote an hour every day to practice mathematics questions. Attend all the classes, pay attention to your teachers, revise whatever is taught in the class the same day, and practice as many questions as possible on the topic. Supplementing it with the NCERT textbook and solving all the practice exercises of the NCERT exemplar can give you an edge.

Keep Asking Yourself Questions: JEE Mathematics tests your acquired knowledge and aptitude. Hence, it is important for you to understand the derivations deeply. Ask yourself questions such as: What is the need for such a formula? What steps or techniques are used to arrive at the conclusions? Where to use this formula? All the rationale behind this should be probed into.

Sort Your Problems: During the exam, picking up problems on the basis of easy, medium, and difficult and attempting them in this order goes a long way in ensuring success as initial success generates confidence and calms down the mind to think more analytically for the remaining more tricky problems.

Important Topics: Thoroughly prepare chapters like 3-Dimensional Geometry, Applications of Derivatives, Limits, Continuity, and Differentiability and Matrices and Determinants as they constitute a higher number of questions in JEE (Main) exam.


Another scoring subject to consider, Physics, much like math, also requires you to be fast, accurate, and smart

Cover Your NCERT thoroughly: Questions in JEE Main are based on the NCERT. Hence, it is imperative to cover the NCERT textbook and its exemplar completely. Reading the theory in detail at least 4-5 times along with practicing all the examples is a must. Additionally, the exercise questions should be solved with great precision.

Supplementary Books: After completing the NCERT textbook, you should refer to ‘Concepts in Physics’ by Dr. HC Verma for strengthening your basics. Beginning with its examples, solve objectives I, II, and the theory questions.

Strong Concepts Build The Best Foundations: Strong conceptual knowledge along with the application of concepts to problems is the key to ace JEE Main Physics. Pay proper attention to your lessons, listen to the teachers, revise the lessons daily after the classes, go through each derivation, prepare short notes for revision purposes and most importantly memorize the formulae, definitions, and processes.

Important chapters: While preparing, pay extra attention to chapters like System of Particles and Rotational Motion, Current Electricity, Electrical Potential and Capacitance, Ray Optics and Units and Measurement, etc. as these are extremely important. On the other hand, fewer questions are asked from Mechanical properties of solids, Magnetism and Matter and Kinetic Theory of Gases, etc.


Chemistry can be a rewarding subject if studied with a plan, and here’s the best way to do it!

Practice Makes Perfect: Practice as many mock papers as possible and with great accuracy and speed. The aim should be to complete the Chemistry paper in the shortest span of time. Every minute saved would allow you additional time for complex and time-consuming problems in Physics and Mathematics.

The NCERT Is Your Holy Book: The majority of questions in Chemistry in JEE Main are straightforward and based only on facts elucidated in the NCERT textbook. Hence, you should thoroughly go through the NCERT textbook along with the NCERT exemplar. Practice every solved example and exercise question.

Important Chapters: While Chemical Bonding and Molecular Structure, Bio-molecules, Polymer, Aldehyde Ketone, and Carboxylic acids, Equilibrium, Coordinate Compounds, etc. constitute the major part of the Chemistry paper, Qualitative Analysis, General principles and Processes of Isolation of Elements and Surface Chemistry, etc. have less number of questions in the exam.

General Tips

  • Give equal weightage to all topics
  • Distribute the time needed to study it. Give more time to difficult topics and less to the ones you just need to revise.
  • Ensure you have scheduled revision time in the plan
  • While studying, make sure to note important points and formulas. These short notes will be useful during revision.
  • After studying a chapter or topic, check how much you can recollect and to what extent you have understood the topic.
  • Then practice questions based on the topic studied. While practicing do not go for the solution directly. Try to solve yourself, make mistakes and then correct it.
  • Use the analysis to know your weak areas and concentrate on improving while revising.
  • Clear all your concepts, doubts. Never leave a question unanswered in your mind.
