If your professors have provided you with a syllabus ahead of time, try to mark where the readings are for each week. The program requires a TON of reading, and once you start classes you will learn how to prioritize which class is more important than another one. I would take the week before school to relax--school is intense, but totally worth it. Best advice would be to stay organized! Write down due dates of assignments, evaluations, and everything for the semester as soon as you know. Stay on top of it. :)
