Hi Cherish, It depends on the program. Programs can have what is called a "practicum," which is a period of time in which they work for a small wage and must perform well in order to graduate. This is typical of professional programs like medicine, law, nursing, business, or some science courses. Other programs are all classes. At the graduate level (Master's or Ph.D), the last year (or years) can be spent working on a project instead of taking classes.
