Hello,

for any exam there is a board. they give the complete syllabus and book list to be referred or can be considered as master book to crack the entrance.

No site can help you until you get your basics clearly and good at solving any question with maximum accuracy. You can take mock test of yourself to test where you stand and where you are book.

The simple way to crack an exam is becoming strong in the concepts. When the situation is competive then you have to cover the whole syllabus or you can leave some part if you are not getting it and try to study in relaxing time and just get the root meaning of that part.

for other you have to skill up like if you get any question from that part you are 100% sure that you can answer it with accuracy. If there is negative marking then don't put guess just attempt where you are sure.

SO just prepare accordingly. Don't look for much resources as they will only divert you rather than to help you.

Books are the best friend who accepts them wholeheartedly. All the best!

Hope it helps!
