Of course, you can go for BSc in Mathematics if you further want to pursue MCA.

Eligibility criteria for MCA : Candidates should have completed their bachelors in any stream (science, arts or commerce) and should have scored at least 50% marks and must have had Mathematics as one of the main subjects in 10+2.
