JEE Main 2021: Subject-wise preparation tips to ace engineering entrance exam

As the JEE Main 2021 examination is approaching this month, here are some important tips on how to prepare for the engineering entrance exam.

Here are the subject wise tips to score well in all the attempts of the JEE Main 2021 exam.

As February has started, it is high time for the students appearing for the JEE Main 2021 February exam to reach the final stages of their preparation. Firstly, students should not think too much about the result and four attempts right now. Keep yourself motivated and surely you will do wonders in JEE all four sessions.

Board exams are set to begin in May and hence, students should focus on creating a win-win situation for themselves in both board exams and JEE entrance exam. A good tip is to divide the remaining time span into two parts.

First division of time span

The first division of time will be from now till the upcoming board exams for class 12 students. This is the core time where you really need to slog for the JEE exams as there will be constant attempts per month.

It is advised that one should study 9 to 10 hrs per day. During these days one should regularly take a mock test and after the test, you need to spend at least 30 minutes analysing it so that you can understand your strength and weakness.

Candidates appearing for the JEE Main 2021 exams can also attempt any subject they are comfortable with. In the remaining six or seven hours divide it into two or three slots for two or three subjects Ideally one should give equal time to all subjects, but you can give a little more time to the subject which you feel is weak.

Normally chemistry is the most scoring followed by physics followed by maths. In this time span, you should focus on class 11th topics because right now you will be afresh with class 12th topics as board exam preparations are underway.

Class 11 topics to revise


  • Thermodynamics
  • Kinetic Theory of Gases
  • Oscillation and Waves
  • Units & Measurements
  • Rotational mechanics


  • Hydrogen
  • S-Block Elements
  • P-Block Elements
  • D & F-Block Element
  • Classification of Elements and Periodicity in Properties
  • General Principles and Processes of Isolation of Metals


  • Co-Ordinate Geometry
  • Sets, Relations, and Functions
  • Complex Numbers and Quadratic Equations
  • Matrices and Determinants
  • Permutations and Combinations

Lastly in the tight schedule of preparation don’t forget to be healthy so avoid fried and fast food, take antioxidants, drink a lot of water and take small breaks after two hours of study. Take a walk or listen to light music and take proper sleep as well.

As per NTA norms, JEE will be conducted four times this year once in February March April, and May and the best of it will be taken into consideration so it is wise to give all attempts so that you can have parity in normalisation of percentiles and finally getting a rank.

Preparation after board exams

After the board exams for class 12 students commence in May, there will be almost no time to prepare exclusively for the final attempts of the JEE Main 2021 examination. A positive point can be that you have already appeared for the exam three times by now so it will be easier.

Candidates will easily be able to score 95 percent marks in the final attempt of the JEE Main 2021 exam and then, they can solely focus on their JEE Advanced 2021 preparation. Candidates must note that they must also balance their studies along with the board exam preparation so that they can score well in both.
