Well, when u keep solving questions of different levels, u would be easily able to identify them easily and know how much time u need to solve a particular type of problem and whether u could actually solve it or not.
Sufficient practice and having a command on the ways to calculate (using vedic maths) should help u clear DI easily.
Not sure about the books for DI. Maybe u could ask ur profs at the coaching centre.
