Sir, presently I am focussing only on questions provided by coaching centre? Do I need to study frst from books and then attempt question bank or it can be achieved thru more practice tests only?
Book is the perfect medicine for any competitive examination. Reading books will help you better understand the concept of subject matter and then solve the problems.
