There's no single answer to the average class size at the University of Florida (UF). The average class size varies significantly depending on the course, department, level (undergraduate vs. graduate), and even the instructor. Some classes, especially introductory large lectures, can have hundreds of students, while others, like seminars or upper-level courses, may have only a dozen.
UF doesn't publish a single, overall average class size figure. To get a better understanding, you would need to look at specific departments or courses you're interested in.
