Hi,
What do you mean by occasional student? If its distance learning that you are refereeing to, yes, you can pursue MCA post completion of BCOM degree from a recognised university either through full time or distance learning with minimum 50% marks at graduation.

You are eligible to apply under general category.

In regular mode of education, attendance is a major criteria. Hence the no. of classes that you plan to miss should be well calculated.
