Hello  Mithilesh

As you want to prepare yourself for NEET

I want to suggest you to take online couching from YouTube from channel BioMentor as according to me he is not only a Doctor but a best teacher for teaching Biology.

For study materials you can go through the Monthly Magazine for NEET preparation that will  cost you low also. And buy some questions paper books and  Continue your Preparation from right now

Hope this will help you
