See every book is good unless the candidate studying the book has all the concepts clear. There  is nothing like repeators. I have seen repeators doing excellent.

First of all you have to be 100% clear in the concepts. For that in chemistry ncert for inorganic and vk jaiswal for inorganic questions. For physical your notes are enough and N avasthi is very good book for solving numericals. For organic you need to have a reference book also i suggest solomons and balaji publication's book is very good .

For maths cengage is good also you can solve arihant books. those are also very good.

Thank you.
