Hello aspirant,

In the last months of preparation, the major thing to do is practice more questions especially on the topics you find difficulty. Work out many question papers and take mock tests to manage time and increase calculation speeds. Writing as many exams as you can is the major trick to crack JEE exam.

Focus a little more on organic chemistry topics and friction in physics as they are important and tricky. Calm yourself and take the best out of you in the last months of preparation.

Hope this was helpful
