Is Ncert enough to be able to do Maths Standard?

I know there are a lot of people from class 10th frequently asking questions, I am not exception. I would like to know if I can solve examples and sums of mcert, will that be enough of a concept clarity to be able to get 95 in maths? I really don't wanna do sums from reference books cuz those might be too high level and even though they may help me practise, they will lower my confidence if I get some wrong.
