@shobhit If you closely look at the syllabus of the CDAC C-CAT exam above, you need to find out which subjects you are good at and at which topics you suck, and plan your exam strategy accordingly. 

You can start by taking CDAC's mock test web application seriously. It is a new feature present on their website, meant to give candidates a little familiarity with the computer administered exam.

Have you checked the prescribed books for all 3 sections on their official site?

Read them all thoroughly and solve the numerical + theoretical questions at the end of each chapter.
