No, knowing computers is not necessary for commerce students.

If you specify the college where you are seeing admission, then I will give you the exact details of eligibility. For now, the eligibility criteria of most of the colleges is to qualify +2 with a minimum of 45% or more.

Dear Sukhjit,
You can do MCA without mathematics in HSC, but only if you have studied mathematics in your B.Com. If you have done your graduation via distance learning, then pursue a 1-year PGDCA and with that eligibility, you can pursue MCA (direct II year) by Lateral Entry Scheme.

Yes, you can easily get admission in Narsee Monjee College of Commerce and Economics College at this score in class 12th but for that, you have to be a little patient as in this college the admission calls will be made after the 2nd week of July.
