Hello Aspirant,

This is a debate which every student has in its mind . But i have gone through this process and I know what can be right for a student. If you want to strengthen your concept you need to read proper theory for that for which you need DC Pandey.

The numericals if you want to solve for practice , you can go for HC Verma. I personally feel the book of HC Verma is not of much use because you can practice the sums from previous years also . That is enough and can practice the coaching sums given by your teachers.
