I have done my 12th with PCM but I failed in physics. Can I get admission for pharmacy?

Yes, you can get. You have to qualify in B.Pharma entrance exams.

Yes, you can get admission in pharmacy, as in the entrance, there is no criteria of passing Physics but you need to pass in Chemistry and mathematics/biology.

Maths is not mandatory but you may have to study maths as one of the subject in any of the semesters in B.Pharma. No maths is not a compulsion. In fact PHARMACY is the only branch where in students of both Maths and Biology can get admission.

If you have passed class 12th, you can get admission in D.Pharm which is a two years course after 10+2 (science academic stream).
