Dear Aspirant,

If you fail in Biology theory, overall you will be considered as fail in that subject, For admission into the Bachelors of Pharmacy course, you need to have 50% aggregate in English, Physics, Chemistry, Biology/Mathematics. If you have Mathematics also, then, you can consider admission into B.Pharmacy, otherwise you need to reappear for the written theory exam.
