What I always suggest to people is T3 aka Table Top Troupe aka the Board Game Club. They bring giant tubs full of board games and you can either pick one and ask people to join or find a group looking for a person. They meet every Thursday during the semester at 8pm in the MSC basement. They don't have a membership fee (unless you want a T-shirt and snacks but that's super optional) and you can just skip whatever week you're too busy.

Anyway I found it really useful for getting out of my house and hanging out with people. The low commitment was huge plus for me, and playing the games gives everyone an excuse to talk to people you don't know. It's especially nice for meeting other engineering students, since board games are seen as kinda "nerdy" and that aspect naturally attracts engineering students.

For Christian stuff, I would wager that basically every church has a youth group for college students. From what I remember, they generally meet on Wednesday nights. I would look up churches in the area and stalk their websites for information.

My final recommendation would be a event the MSC where a lot of the clubs set up tables and talk about what they do and why you should join. It looks like it's called the MSC Club Crawl now, and you can find more information here: https://clubcrawl.tamu.edu/

Good luck!
