Hello Kunal

You can definitely get admission in good colleges for BCA, as most colleges/universities demand candidates that have a minimum aggregate of 50% in the qualifying examination of HSC from any recognized board or university. Plus, if you had Mathematics as one of the subjects, then it is going to be the icing on the cake, as there are some institutions that demand Mathematics to be a compulsory subject in HSC.

But in general, most colleges don't demand Mathematics as a compulsory subject in class 12 for BCA. They select candidates on the basis of merit, and some colleges also conduct entrance examinations and personal interviews on their own in order to determine the capability of the aspirants.

Regarding MCA, I would like to say that yes, you can pursue MCA from a good college too. For pursuing MCA, you should have studied Mathematics in either HSC level or Graduation level. As you already had Mathematics as a subject in HSC level, you can easily get a chance to study both BCA and MCA in a good institution.

Good Luck!!!
