I would suggest you to pursue MBA full time. MBA is for those who seek a university programme to get a holistic view of the programme. As far as the industry is concerned they recognise talent from the institutes of repute rather than bothering whether it’s an MBA or PGDM.

Yes, you can apply for now as most of the colleges have started their registration procedures.

MBA would add more value and would prove to be more helpful for those, who have previously worked somewhere. A person with a relevant work experience, knows things like industry structure, code of conduct, accepted norms, current trends, etc., which a fresher lacks.

PESIT is a better college than the others.

Yes, you can get it through management quota.
