How to Revise Physics for JEE Main 2021 in Just 1 Month?

If you are wondering how to start your revision for Physics for JEE Main in order to crack the JEE Main exam 2021 in 1 month, we are here to help you in the best possible manner.

We have everything you need, from the complete syllabus of physics to important chapters in physics and weightage of chapters to a number of questions asked in the previous year’s examination and then a 1-month revision plan of physics for you.

With JEE Main 2021 scheduled to be conducted sometime in 2021, most probably January 2021 and April 2021, you will have just one month left to give your one-year preparation a sure-shot success.

Building the revision plan of Physics for JEE

In your JEE Main 2021 exam pattern, the Physics section takes first place in the question paper. As you must be aware that the Physics subject is the highly competitive section and scoring well marks in the subject should be easy and quick if you are able to tightly hold the concepts. So, before jumping to the last-minute preparation of the Physics subject, let us look at the syllabus of the subject first.

JEE Main 2021 Physics Syllabus

The complete syllabus for Physics carries a weightage of 30 marks on the JEE Main exam 2021. The Physics syllabus is further divided into two components Part A and Part B. Part A will test your theoretical knowledge and carry 80% weightage whereas Part B tests your practical component and has 20% weightage. There will be no change in JEE Main exam syllabus and pattern for every subject. We are providing you with a revision plan for the subject Physics for 1-month preparation.
