Hello student,

If you want to learn 10th class Maths deeply, then your basic concepts must be very clear. So,  first of all start from NCERT Mathematics book. In the starting of any chapter, some theory part is given. Read it thouroughlly and then move to exercise questions. When your NCERT gets completed, then move to some other higher level book.

RD Sharma Maths book , will be a better then . Solve as much problems as you can. Solving more and more problems boosts your confidence. If you cover both these books, then surely you have a very great hold on class 10th maths. You can also use some online resources for better concept clearity like You Tube, Unacademy etc.

Hope this helps.
