As far as money is concerned then according to me MBA after b.pharma is one of the best option to exercise. I am not saying that there aren't any other fields, there are but money is much there.

After your graduation you can simply take admission in tier-1 colleges for MBA like top IIM'S after qualifying CAT cutoffs.

You can also go for m.pharma or Pharma D after your graduation.

All the best!!
