I am currently in class 12 studying in a local coaching where they don't teach well, so I study on my own. I am very good in physics, decent in chemistry and not so good at maths, the reason is I don't know how to study and from where to study it. I have completed the whole syllabus of maths and know the basic theory. I have Objective Rd Sharma, but I don't think it is that good for jee adv. I see that problems in it are nowhere near to the level of problems in Allen test series. Please suggest me right books/material/ to build a healthy score in maths.
I am enrolled in a dummy school so I have a plenty of time.
Thanks in advance..
