Dear candidate as per the B.Pharmacy syllabus given by PCI you have a theory non University ( marks given by college) paper in the second semester on Computer Application where you need some basic computer knowledge. But in the final year paper you have an optional subject Computer Aided Drug Design, for that you need deep Computer knowledge. If you plan to do Masters in Pharmaceutical Chemistry then only you need knowledge of JAVA and more. But if you wish to skip this part, you do have a choice.

So don't be worried, move on !!

Good luck!!
