If you want to earn highest salary just after your graduation then I think you should choose Computer Science and Engineering because if you do Computer Science and Engineering from IIT such as IIT Bombay IIT Kanpur IIT Guwahati IIT Kharagpur IIT Madras IIT Delhi then you can get a package of upto 1.5 crore per annum from the campus itself that 2 in just 3 and half year therefore I don't think did just after graduation you can earn this match with any other degre therefore try for IIT and computer science and engineering but I must tell you hear that to get Seat into IIT with a computer science and engineering course you need to be hard working as well as conceptually very strong.

To get into IIT you need to first appear for JEE main and qualified it and then you need to appear for JEE advanced and get a good rank of under 500 to get a seat in to this IIT with computer science and engineering also please make sure that you a score at least 75 percentage in your class 12th.
