Create a fee invoice application for students attending Valence College, a college in the State of Florida. 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. Each Ms and Phd student must be a teaching assistant for one undergraduate course. MS students can only take graduate courses. A course with a Course Number (crn) less than 5000 is considered an undergraduate course, and courses with a 5000 crn or higher are graduate courses.
