I'm in my final year and college life is about to end in next 20 days, Any must try things before college ends?

Convince your friends to go on a trip, it'll be the most memorable one

spend time with your friends as much as you could and go on a trip on weekend and do some unforgettable thing before leaving campus and

one tip which you will be needing after college:
no matter what don't stop reaching out to your people.

Spend more time with friends and your favourite faculty, plan for a short trip if possible or atleast lunch outing with all your friends together

go smash that professor's car window

Talk to the person you wants to and never did.
