I had gone through almost all kind of books during my preparation phase so my opinion might be helpful for you.
•Yeah DC PANDEY is a good books solve its exercise and examples thoroughly
•Give mock tests as much as you can if you found physics tough then take a paper daily ( even I did this)
•Make a formula notebook
• Note down your mistakes
PS- In my first attempt I scored 120 but in second it is 165 because I followed above things and you need not to do errorless .
