Dear Aspirant,

if you are preparing for any objective exams,My first suggestion is to use ncert books, because ncert book key or solutions are considered as the final answers for most of the exams. different types of patterns of objective bits were also given in the book. If you are a neet or iit aspirant use AKASH series books after completion of using ncert books to cover maximum number of questions in a topic

ALL THE BEST DEAR!!
