Hello ravindra

You can follow your normal ncert and if you want to solve many problems, you can buy books like elementary problems in organic chemistry, above that you can buy notes from many shops in which you can get everything in short and very meaningful way.

It's very important for good marks that you try to solve mock test papers before NEET exam, they will improve your overall performance and increases the chances of getting high marks.

I hope it helps

Best of luck
