Hello!

BITS is a very prestigious college in itself. It is the most sought after college after NITs and IITs. The placements are quite good.

M.sc economics from BITS,Pilani is a very good choice. the previous year highest package offered was around 20lpa. Being a dual degree student would surely provide you perks but not being one should not be much of a trouble. You can still excel and be at par with the dual degree students by improving your soft skills and maintaining a good score. Be confident with whatever you've choosed to do.

All the best.
