Congrats. Based on my personal experience, let me give you some advice.
MAINTAIN CONTACT WITH YOUR UNIVERSITY FRIENDS AT ALL COSTS.
It's not going to get any better than this after university. Don't make my mistake and get socially isolated for decades. Even if you made only one or two friends in university, keep them as close as you possibly can. You need friends to make friends, just like you need money to make money. And for friendships there's no charity.
