Hi,
Best colleges in India to pursue Computer Science engineering are:
IIT DELHI
IIT BOMBAY
IIT KHARAGPUR
DTU
IPU
Manav Rachna University etc.

If you have a graduation degree, that would be enough for you.

Only in private colleges! They do take admission on the basis of board percentage and donation as well!

Computer Science is the best course from NMIMS in order to placement.

Hi Priya,
Every college has reservations for SC / ST / OBC etc. However, you need to contact the institute officials personally for specific admission details as it differs from one college to another.
I hope this information helps. Please feel free to revert.
Wish you luck.

You can't compare as both are different fields and both have good scope as well. Testing is required in almost every company. Database is core part of any big application. I would suggest you to take more efforts in database as you can move to testing later on also but it is not possible that if you opt testing now and want to make career in database after some time.
