I have got 8.5 CGPA in B.Pharm. Which colleges are the best for me? Also, tell me about the entrance exams for MBA pharma?

Your percentile is good enough. MBA Pharma is a good option, you can do it from Jamia Hamdard, Delhi.

You can also consider IES Management College, Bandra, MUMBAI. They have 2 year full-time Pharma MBA with option of choosing specialisation between Pharma & Healthcare/Hospital Management for 2nd year. Both paths are suitable. Depending on your interest and inclination, you may pick one.

B.Pharma + MBA in health care will give you good opportunities. Also, qualify MAT and CAT with a good score and look for some excellent colleges like MSR, RVIM, CHRIST, Welingkar for admission.
