Finding your niche in college?

Ive been in college for a little over a week. I’m more of a quiet, low key sort of person. I don’t like to party that much. I also feel like I take longer to get to know people than most. Some of the girls I know are already like hugging each other and telling secrets and stuff and it kind of freaks me out. I’ve mostly been hanging out with the people around me in my dorm. They’re perfectly nice. But I’m starting to realize that I really don’t have that much in common with them. I was just wondering how people actually start to find people with similar interests and personalities. I guess I’m kind of nerdy. I like Star Trek and Harry Potter and cartoons. But I like to do other stuff and I’m perfectly willing to go out and party occasionally.
I’ve joined a few clubs but the haven’t met yet. And I’m in classes that are mostly lectures with with like 75+ people in them so it’s kind of hard to meet people there.
So what I want to know is where to go to meet nerdy kids on campus?

This is a longer term solution, but some colleges have special interest housing that might be themed in a way you would like. Some co-op housing on some campuses also get a fair number of nerdy kids. Once the clubs start meeting, that may help. Maybe think about getting a part time job someplace that might draw in nerdy people?

Clubs! My school has a book club, engineering clubs, fandom clubs…

There are sororities at some colleges that are not all about partying and fakeness. You should talk to people around campus and see if there are any that have “nerdy”(nice) people in them.
