Eligibility Criteria-
For all the colleges mentioned above requires 45% or above in your class 12.
* Personal View:
I want to suggest you that you can even persue Btech which will be a good choice because it add more value than BCA in case of package , knowledge and exposure.
For taking admission in Btech in some of reputed colleges like IIT,NIT,IIIT or some good private universities or institute you have to give jee-mains and jee-advance or you can give private universities entrance exams for getting admission in some good private colleges.

If you even after want to study BCA then I will suggest you to check for National Institute of Management (NIM), Mumbai.
