Hy,
I understand your situation your buddy. You are not getting a way out to make your studies useful.
Well in my opinion all you can do is firstly focus on your studies as they are the priority.
Secondly you need to figure out your interest areas like marketing, finance, human resource management, etc. Then according to your preference you can search internships opportunities on web portals like indeed or internshala, etc.
Thirdly, you can read business articles in newspapers and participate in inter college fest that organised on regular intervals. Do share your college details then I will be able to help you more about this matter.
Just keep on going and search the options that I have told you.
I wish you all the best.
Cheers !!
