Does your Uni have a student union bar or places where everyone goes. Go to them! Get to know people by joining a group or sports team or something. I went to Uni of Wolverhampton and even they seemed to have a team or group for countless sports and hobbies.

There is PUA stuff dedicated to college game, maybe someone on here can point you in the right direction for that?

Quit backwards rationalising why you have a poor social life and do something about it. You can do stuff outside of uni as well. You are only there 2 days a week so you have plenty of time on your hands.
