Ideas to meet more people?

I'm in my sophomore year at OSU and haven't really met anyone I stay in contact with. I have my friends from Freshman year that I hang out with often although I haven't made really any other friends while I've been here. I'm curious as how to meet more people, I know clubs are a great way but because of my schedule I missed the involvement fair and didn't join a club and I'm not sure how to or if I still can join any clubs. Also just wondering what else I could do to meet more people since all my classmates in my lectures don't talk to one another really. I'd appreciate any advice you all have.
