Hello

You can Start solving previous year question paper of CSIR, you will get to know about the question pattern of the exam and difficulty level of the exam.

I would recommend you to Focus more on quantum mechanics related subject like nuclear, statemech and atomic and molecular physics, I think these papers are enough to crack for net.

Manage your time efficiently and revise things multiple times.

Make short notes for effective and fast revision.

Please refer to one of the best study material according to your understanding level.

Give mock tests as much as you can..
