Hi,

if you are doing BCA without any math. But you are doing bca after MCA,then it is must required math for MCA,so you are not eligible for MCA. Every college or institute are required minimum 50% with math in 12th or any bachelor degree.

Yes you can do MCA if you are from Commerce background, but just remember some premier University prefer either Computer ( IP or CS) or maths in +2. So if you have any one of them in +2 you have no issue while applying for admission in BCA & MCA.

One can pursue MCA after the completion of bachelor's degree. Basically, the graduates of Bachelor's of Computer Applications (BCA) pursue MCA. The course emphasis on latest programming languages and tools to develop better and faster applications.

Hope this helps

Wish you luck
