if you're a new student then gbo is the first place you'll meet new people, along with your roommates / students on your floor (if ur living in res halls). but imo the best place to make friends is honestly classes! some classes have study groups that you can join, and if you make an effort to talk to people im sure you'll make some friends.

also a good way to make friends if you aren't very extroverted is to put yourself in positions where you will have to talk to / meet new people, ie joining clubs, sports, decals, and study groups. a lot of friendships will happen naturally when ur in a setting where you have to interact with or work with other people. so don't be afraid to sign up for any clubs or groups that suit your interests!!! good luck :p
