Standard maths is not a different math it is just a math but with a different name. So #prepare your self for board not as you choose standard/basic math #firstly solve ncert questions and main thing is also solve the examples that is also important#then solve reference books (RD.Sharma)
Continueity is most important ,you will have to solve 30 questions per day and don\’t forget all questions of ncert are impotant.
Solve all example questions of Rs aggrawal then you of course will success
Keep prractise from side books
