hi,

most of the bengali medium students face problem in question understanding. as they always accustomed to give exam only in bengali language.so first of all start relate with the terms which is use in physics, chemistry and mathematics. most of the understanding problem occurs in chemistry , compare to mathematics and physics. you may not face much difficulty in physics if you have hc verma physics books. this book is mandatory for jee preparation. see if you are in 12 now I would suggest you to prepare if your 12 preparation is really good. unless you can face problem in board exam. you may give jee advance next year but board exam is not possible to attempt in 2 times. tat macgraw books is best for jee main and advance preparation.

hope you may understand.
