Dear Anusha,

The time left is not very much enough to start again but if you have the determination then you may do it. Solve questions as much as possible as they will show you the type of question and also the concepts. Go with NCERT as much as you can and start attempting questions including organic chemistry too. Make a schedule because it's very much needed now as NEET is next month. Don't be afraid believe in yourself and go for it.

Regards
