That good I think for prepared for NEET you may take help of you NCERT. So it may give some rough figure and I suggested that you focus on 100 % on your Bio and Physics because it is the subject in which you score 100% and in chemistry, you may live or study later after you complete you syllabus is organic chemistry because it takes most of your which I think not valid for that topic in that time I study or some another topic. So you may get some basic. Start your study with your NCERT. Study in your me-time is the best option because at that time you more focus on a single thing.

All the best.
