There are two types of students: graduate and undergraduate. Out-of-state undergraduate students pay twice the tuition of Florida-resident undergraduate students (all students pay the same health and id fees). A graduate student is either a PhD or a MS student. PhD students don't take any courses, but each has an advisor and a research subject.
