The most popular student activities is fraternities and sororities. These give students the most opportunity to become involved around campus and meet some people. Additionally, we have a large number of student organizations. This allows students to become involved in an issue that is important to them.

There are over 300 student organizations on campus, not to mention intramural and college-level sports teams. I am involved in both the Student Longboarding Association, the OU Mascot Team, University Singers, and the Non-Profit Leadership Student Association. The Longboarding Association meets up and goes for group rides and board maintenance projects. It's a great way to meet new people and hang out with people with similar interests. Not everyone leaves their doors open, but all the friendly people do (like me!). I met my closest friends through University Singers and various other organizations. Parties are constantly going on, but they are predominantly centralized in the Greek community. Hundreds of events happen all semester, every semester. There are plenty of things to do on weekend nights besides drinking, including club activities and hanging out with friends! The Union Programming Board is an organization that spends all of it's time and energy working to create fun events that all OU students would enjoy. While there is a mall, Main Street Norman, and Campus Corner, there are so many things going on on-campus that people rarely go off-campus.

The most popular groups on campus are the greek organizations, but outside of that the College Republicans have the largest membership. The most common activities on campus seem to be drinking and studying, but there are many things to do outside of that (I personally enjoy frisbee golf). There are plenty of ways to get involved on campus, whether it be through a greek organization or one of the 100+ clubs. I would say that the average student at OU drinks a considerable amount. On the weekends, students who are under 21 typically attend house parties, which are plentiful around campus. Students who are of age go to Campus Corner, which is the primary bar area for OU students. I personally enjoy going to places such as Logan's or Brother's on Campus Corner, but there are plenty of options outside of that. There are also bars on Main Street, which are frequented by locals and hipsters. As far as things on the weekend that don't involve drinking, there are usually activities at the student union such as movie nights. Drugs are fairly common at OU, but are usually not out in the open.

Greek life is very popular at the University of Oklahoma. Some go as far as to say OU is a greek-run school, but I would not go that far. There are plenty of other organizations that have great participation that do great things for the community. Many students are involved in the University of Oklahoma Student Association, OU's student government. However, not all of these students are political science majors. They are engineers, event planners, marketing majors, business majors, and so much more. They help plan and put on all kinds of events for the campus body as a whole: Welcome Week, Dance Marathon, College Bowl, a speaker series filled with all kinds of interesting topics, Homecoming, University Sing, and a film series shown at the student Union. The students at OU are, as a general rule, very open and friendly. You can find them laughing over a late-night breakfast fun in a dining hall or playing glow-in-the-dark ultimate frisbee on the practice soccer fields. People at OU find their best friends by getting involved in something they love, whether that be Cake Club (yes, we actually have one of those), Quidditch Club, student government, greek life, theater, dance, or any number of multicultural groups.

Fraternities are a large part of the activity in Norman, but they are not the only thing to be involved in. I haven't been in a fraternity and I've had no shortage of things to do. Freshman year was great for me, because living in the dorms was a blast. I roomed with a guy that I didn't know and he is now one of my best friends. I actually still hang out with a group of guys that I met in my hall just because of our proximity while living in the dorms. Even if you aren't great friends with your roommates, there are still a lot of different activities that you can be a part of. There are about 300+ student groups on OU's campus. One of my friends joined the ultimate frisbee club and has been competitively competing with other colleges. I actually joined the rugby club and was able to play for a year and make some awesome friends there (unfortunately I had to bow out due to injuries). There is also a great music scene here in Norman. Local bands play a lot of shows on or near campus, making it very easy to find great music without having to pay a lot or travel far. I'm also involved in a campus ministry with my church, Antioch Community Church. I've grown really close to the people that I've met within the ministry and they have become my second family. There is no shortage of faith-based/religious groups, this being the Bible belt, but thankfully there is not a climate of dissent or hostility directed at those not involved.

It's hard to tell which is the most popular organization on campus. But the Union Programming Board is an organization that include every students in its events. They have, free movies, free food, concerts, and they also host the annual foam parties. I'm involved with the OU Rugby. The team is pretty good and the players really get along with each other. We also compete at the Collegiate Premier Division level. Most of the sports events are free with valid OU student ID. I met my closest friends at the dorms and we still hangout. People party every week, literally. If you don't drink, you can always hangout with friends on Saturday nights like private parties, watch movies, play pingpong or pool, etc.

The most popular student organizations on campus are Greek life and student congress. Many undergrads choose to rush a fraternity or sorority. Also, the student congress, called UOSA, is an extremely active organization, with many students choosing to participate.
Football is HUGE at OU. Whether or not you are a football fan, you are guaranteed to have fun at an OU foorball game! They are by far the biggest athetic games that students attend every year.
There are performances and other activities that are available to students if you choose to participate. Theatre and dance hold performances all the time. There are movies that play in the union every weekend. The Huff (our recreation center) is always busy with students.
Whether you like to drink or not, you can find other students and groups that are like you. There are people that like to party and drink, but if that's not your thing then you could easily find other people like you.
