Hi Aspirant

A lot of dilemma students face this kind of dilemma. The most important thing here is to pursue your interest.

Although BITS Pilani is one of the best colleges of the nation you must realise what is the relevance of B. Pharma with respect to the future degree that you want to take up.

If you want to pursue MS in the future especially in CS related subjects it would be better if you take a bachelor's degree related to CS.

Consider your other options and then decide what you must take up in the future.

Hope this helps. All the Best.
