The University Quad is a large green space that sits amidst many academic buildings like the College of Science and the College of Letters, Arts, and Social Sciences. Each College has separate commencement ceremonies, but all of them take place here on the University Quad at different times over the course of three days in June. During the regular school year, you may stumble upon a variety of academic-oriented fairs set up on the lawn such as a Graduate & Professional School Fair or an Engineering/Hi-Tech Job Fair. A free shuttle bus called the Bronco Express has multiple routes that travel around the perimeter of the campus, particularly on South University Drive, which conveniently runs along the University Quad.
