im in class 10 and my concepts till class 10 are clear. i want to start preparing my base to study tougher topics for iit.which books should i use? they should be easy to understand as for now i just want basic knowledge for iit preparation.

see my brother be confident and for maths do RD SHARMA THORUGHLY and for physics prefer HC VERMA 2 VOLUMES and for chemistry PREFER OP TANDON BOOKS.its more than enough to prepare and you are also having two years for iit entrance so dont worry.
