Hello Kishan,

Revising from R. D. Sharma and NCERT is quite sufficient to get a good rank in JEE Mains but if you are confident enough about answering the questions in these two books then you can move on to S. K. Goyal and practice some new pattern problems there.

Always remember one thing that it's always best to know more than the syllabus but have a good grip in basic concepts first then practice basic problems included in your syllabus.

After all that done then go for new pattern books that contain beyond the syllabus questions.

Hope this helps. You can contact for any further guidelines.

Yes RD Sharma is best recommended for indepth and lucid and crisp problems which is more important and has best recommended by toppers.

Even Objective Ncertbooks books are great.

Solve maximum mock exams from previous years which are must.
