To study B.Pharmacy you need to have pass 10+2 with Physics, Chemistry, Mathematics and Biology( better to have ) and if you wish to study in any college of your own state then you must appear for their state Joint Entrance Examination and if you wish to study in other states check the Eligibility criteria of the Joint Entrance Examination of that state or can appear for JEE Mains as well, but you make sure the college that you prefer should allot seat for JEE Mains quota students.

Good luck!!
