From your profile it is clear you are a pharmacy aspirant so i am providing information of it.

To pursue a pharmacy course, usually a minimum of 50% aggregate marks in 12th grade science stream with Physics, Chemistry, and Biology/Mathematics is required for admission, depending on the institution and region you can check from PHARMACY ELIGIBILITY CRITERIA

If you have less than 50 percent in your 12th you can opt for Diploma in Pharmacy (D.Pharm) in which You need to have passed 10+2 with a minimum of 35% marks in the science stream from a recognized board. The cut-off percentage may vary by college or university.

You may also need to qualify for entrance exams like WBJEE, GCET, HPCET, State-Level Common Entrance Tests (CETs), University-Specific Entrance Exams, or National Eligibility cum Entrance Test (NEET).

The difference between these two courses is diploma is of 2 years and b.pharma is 4 years and later course has more strong base in practical skills and theoretical knowledge for a career in the pharmaceutical industry.

Good luck..
