which book shall i go for 11th grade math ,following both cbse and jee patterns?

Dear Shivani,

First of all  Prepration does not depends on books, it totally depends on you, how much you are clear with your topics.

For basic clearance you need to go with "R.D.Sharma" or "R.S.Agarwaal"  and for the prepration you need to switch some higher level books such as"Tata MCgrew Hills" or " M.L.Khanna"

Askiitians also provide you one of the best study material and online interactive classroom coaching.
