MBA/PGDM

CS & CA are professional qualifications and have more weight age from a qualification perspective. It makes you a specialist in the company law/ accounts & finance domain and you can also start your own practice. Whereas MBA gives you exposure to general management principles and gives you an opportunity to explore a career in general management. Each qualification gives you a different career path. The decision here would depend a lot on your interest areas and career aspirations.

A MBA in your work area is beneficial or else if you aspire to explore a new area than you should pursue your MBA in that area. A MBA in ones area of interest is always advisable.

The minimum qualifying percentage requirement for MBA is 50% at graduation level. Since you have scored 40% you can explore the following:

2. Pick up a work assignment & after gaining 3 years of work experience enrol for a part time MBA, distance MBA or Executive MBA
3. Enrol for M.Com and score more than 50% marks in it and then explore MBA based on your M.Com score.
