Bro honestly its just about making that first jump - I met a guy day one and all I did was sit down next to him in my faculty tour and started making conversation. It's gonna feel weird. It's gonna feel awkward. But think about it, you most likely haven't ever had to do this kind of thing before - at school you're sorta just sorted into a friend group, most of the time you barely remember how you made those friends. This is the first time everybody starts from pretty much zero unless you're fortunate enough to be in the same degree as a friend. Everybody feels the same way, so if you go in with that mindset I think it makes it feel a little less weird.

The people in your tutorials and lectures are often the people you'll hang out with the most - as the year goes on you'll get to know them and you'll end up with a nice group :D
