Hii there,

Dear candidate please edit your question, it is not quite clear. Though I would like to answer few points about books on jee advanced. There are very few books which cover almost all the theory part of JEE Advanced syllabus completely. So I would suggest you to have a look at the syllabus particularly covering all topics, going one by one and finding them in any of the books, and then go for solving sone tough questions from sample or questions given related to topic.

The link provided below provides some best books for Advanced
