Subject-wise preparation strategy
Preparing for a single subject or a few topics is not enough; it is very important to maintain a good command over the main topics. The following is the subject-wise coverage that you can refer to:
Devote more time on factual topics like Organic Chemistry, Polymers, Coordination Chemistry, Surface Chemistry, D&F Block Elements, P Block Elements, Chemical Bonding, Mole Concept, Atomic Structure, Equilibrium, Electrochemistry, Ores and Metallurgy.
Make sure you have a good command and solving speed for numerical. Study Mechanics, Electricity, Magnetism, Optics, Semiconductors, Communication Systems, Thermodynamics, Fluids, Electrostatics, Electromagnetic Induction, Waves and Sound, Magnetics, Kinematics Thoroughly.
Write down all the important formulas on a sheet and keep revising them at regular intervals. Maintain a good problem-solving reputation in Conic Sections, 3D Geometry, Calculus, Quadratic Equations, Linear Programming, Progressions, Limits, Continuity and Differentiability, Matrices, Complex Numbers, Coordinate Geometry, Permutations And Combinations, and Probability.

Preparation Tips and Tricks for JEE Main
Starting your studies without a direction is a waste of time. Equally crucial is a well-planned preparation strategy. Ensure that you follow the correct path and make the most of your precious time:
- First, avoid all kinds of distractions. You’ve got to put your phone down for your own good. Just focus on studying rather than what’s going on in Social Media.
- Pay more attention to class 11th concepts as the study material for class 12th would be fresher and more revised. (45% of the syllabus is from 11th and 55% from 12th)
- Try to do as many quality problems as possible to develop a good confidence level.
- Increase the frequency of taking mock tests to get familiar with exam pattern, time availability, speed, and accuracy.
- Revision is extremely important. Make sure that you are preparing revision notes for the important topics you learn or read.
- Spend more time in solving previous year question papers, preferably in the real test environment.
- Focus on the weaker sections to identify areas of improvement for efficient JEE preparation.
- While studying, make sure you are spending quality time. The focussed and dedicated attitude of one hour is more worth than long hours of diverted attention. Also, relax completely while taking breaks.
- Don’t push yourself for overstressed or underslept hours. Take power naps often to keep yourself recharged.
- Speed and accuracy are very important. Measure these factors effectively while taking practice tests.
- JEE exam is divided into 3 difficulty parameters: easy, moderate and tough. Try solving the easy and moderate ones first and then devote your time to the tough ones.
- For getting a better rank, you need to read “3-month plan to crack AIR 500 in the JEE“
- Take sound sleep of 6-8 hours the previous night.
- Keep an optimistic and positive attitude.
- Don’t discuss much with your friends about the preparations.
- Revise all the important formulas.
- Carry medicines if you require them, being ill during the exam can dent your chances of securing a good rank.
- Have a good breakfast and don’t go hungry to the examination hall.
- Reach the examination center at least half an hour before the reporting time.
- Read the instructions mentioned on the admit card carefully and take all the required stationery items along
- Don’t panic, even if you feel that the exam is tough. It is the relative performance that counts, and you will do awesome, champ!

Calculating JEE Main 2021 Score
Here is how JEE Main score has been calculated:
- The scores given are based on a scale of 100 to 0 for every session (January & April) of the exam. The topper of each session has been given a percentile score of 100 and based on it and the relative performance of candidates, the percentile scores have been allotted.
- The highest score in each session of the exam has been normalized with a percentile score of 100.
- In case of a tie, the scores have been settled in the following chronological order:
- Candidates with the highest percentile score in mathematics.
- Followed by candidates with the highest percentile score in Physics.
- Followed by candidates with the highest percentile score in Chemistry.
- If the scores are still tied, then finally the age of the candidates has been considered while allotting a rank. In this case, older candidates have been given preference.
- In case the tie persists then the candidates have been given the same rank.
- The scores of each session have been merged (January & April) to compile the overall score.
- The better percentile score out of the two attempts will be considered as the final result.
