I am studying 11th class.How I have to prepare for Mains and Advance.Which books are best for Mains examination
First of all, Start from basic books like NCERT.Follow a proper timetable and give equal time to all three subjects.Practice NCERT BOOKS and try to remember concepts as this will help you to solve problems.maafter completing it, you can practice other books like HC VERMA for physics, OP TONDON for chemistry and RD SHARMA for mathematics.Practice as much as you can.
Solve previous year's question papers and sample papers.Be motivated and consistent always.
Good luck.
