Hello Rohit ,

As you said you're left with just only one month for the final exam. You can choose the following way.

Firstly try to clear all your doubts and basis concept within 4 to 5 days.

After that take all the previous year papers of JEE Mains or previously AIEEE and try to solve each paper on one day at a same time when you have your final exam of JEE this will help you to have a sitting of continuous 3 hours and also it will help you to keep your mind active in that period. After doing that try to clear your doubts you face while solving the paper.

After solving the paper, in the time you're left after solving the paper try to revise the formulas and study all the subjects.

Hope this will help you to score high. Feel free to ask any query.
