I registered in MBBS and I want to register in B Pharma also. Do I have to register in B Pharma separately?

Yes, you need to register for B.Pharm separately. For MBBS, GGSIPU accepts national-level examination scores, i.e. NEET UG 2022. For B.Pharm, you need to appear in The IPU CET 2022. If you wish to apply for both these courses, you need to apply separately and meet the required admission criteria.
