I am very confused what to do next after my graduation.
Hey Akshat,
As per your below description. You Seems to be interested in Both Fields Of Commerce and Science. So If You have done Graduation From Science Background. Let's Suppose Btech then if you want to do MBA Then it's Great as well. And If You Want to Expand your Science Knowledge Then Go For Mtech But I'll Suggest Try To Get Into A prestigious college For Both MBA and Mtech. And if you have doing your Graduation From a non-Computer Branch then you should start Learning at least one programming language.
Best of luck
