It really depends on what kind of school you go to. If you attend a prestigious, Ivy League university, it may be a little more difficult to find a party than if you go to a state school with less stringent admission requirements.
But generally speaking, most schools have some sort of party scene, and it’s usually not too difficult to find something going on. If you don’t want to deal with the hassle of going out, there are always plenty of parties happening online that you can join in on without ever having to leave your couch. Just be sure to use caution when meeting people on the internet in person!
