Having trouble finding friends

I’m having trouble finding friends/study buddies. The only person I know is my bf. I wanna find some Female friends that are taking criminology like me or have maybe some of the same classes as me so we can help each other out. I’m 18 if someone asks and I’m a first year. It would be great if someone would reply, no weird shi from me, I honestly just wanna find ppl to hangout with lol
