DON'T GO TO CURAJ FOR M.SC CS.  I canceled my admission from there after attending 3 days there. Teaching quality there is pathetic. I would not recommend it to anyone at all. The campus is located in a remote area (in farming-lands on a highway near kishangarh).

Hello Ritu,

You can practice your course books, previous year sample paper or question papers. Some reference books are mentioned below:

• Computer Science Introduction to Wolfram Mathematica by Ilkka Kokkarinen
• Foundations of Computation by Carol Critchlow, David Eck
• Building Blocks for Theoretical Computer Science by Margaret M. Fleck
• MCA Master of Computer Applications Entrance Exam by R. Gupta
• Introduction to Soft Computing by Eva Volna - Bookboon, 2013

Good Luck!
