Can I do B.Sc and D.Pharma together from 2 different colleges?

Dear, You cannot pursue 2 Regular programmes in the same duration. As per UGC guidelines, you can do 2 different courses from 2 different universities in 2 different study modes (regular and distance). You need to decide accordingly. All the best

If you have the potential to manage both the course, then do the same. Both the courses are poles apart, so you don't need to worry about dos and don'ts.
