A fee invoice for an MS student should look like VALENCE COLLEGE ORLANDO FL 10101 The purpose of this project is to create a fee invoice application for students attending Valence College, a college in the State of Florida. There are two types of students: graduate (PhD and MS) and undergraduate. An out- of-state undergraduate student pays twice the tuition of a Florida-resident undergraduate student (all pay the same health and id fees of $35). A graduate student is either an PhD or an MS student. PhD students don't take any courses, but each has an advisor and a research subject. Each Phd student must supervise at least one lab. A lab can be supervised by more than one PhD student (Labs can't be supervised by undergraduate students nor MS students). MS students can only take graduate courses, and undergraduate students can only take undergraduate courses.
