Dear student NCERT is a baseline you have to do NCERT anyhow it is it is very important and maximal equations revolve around NCERT . rest obviously you have to read other books biggest NCERT is not sufficient if you really want to obtain good marks . As competition is really increasing every day and to get marks out of 720 . I hope this was helpful to you

Hello,

The NCERT Book is fully sufficient for Biology and Inorganic chemistry. For the other parts of chemistry and also for physics, you need to refer to extra books besides NCERT . You may practice physics from H.C. Verma and chemistry from Dinesh's book. Do not forget to practice previous year papers. All the best!
