It's a large university with a diverse student body, meaning there's a range of activities and interests represented. Many students are focused on academics, athletics, research, and various extracurriculars. However, the presence of a large, passionate fanbase (especially for basketball) contributes to a spirited and sometimes boisterous atmosphere, which can involve social events and celebrations.
So, the answer is nuanced: It has a strong party culture alongside a robust academic and extracurricular environment. Whether it's *primarily* a party school is a matter of individual perspective.
