What package can one get after completing b.com along with cs?

I feel you should focus more on gaining experience with large corporate houses instead of package in the initial phase of your career. Once you get good knowledge with hands-on experience, higher salary will be the by-product.

CS is one of the best professional course. Highest paid CS fresher package is 10 lakh p.a as of now. And it will be increasing with your experience and knowledge. And one can get bear minimum of 25000 p.m.
