MCA

Firstly try to crack govt universities exams like IP University, JNU, etc.
If you won't be able to crack these exams then there are many private institutions or universities you can apply to! They take simple entrance or interview.
Every state and cities have many of the good private colleges. It depends on you that which state or city you prefer.
Good luck!

Yes, you've done your B.Sc with computer science then you are eligible for MCA. This year, govt. universities' admissions for MCA were closed but there are many private colleges where admission is going on.

No, try for M.Tech instead of MCA, which (MCA) at times is considered equivalent to B.Tech.
