Ideally, if you take M.Sc. Economics now at BITS Pilani Campus and are able to convert into BE CSE or EEE, the following year with Dual Degree in Economics, thats a win-win situation. If youre Academically strong and confident, as well as Pilani is in Vicinity of your Hometown, or youre anywhere from the Central/Northern Part of India, prefer BITS Pilani. Otherwise, incase youre good to go with EEE, BITS Goa Electrical is a Nice Option with Good Placements, youll even end up saving a year.
