Learn to prioritize your classes in regard to study time.
Not all of your classes will be intensive for you. Those classes that you excel in, are often easy for you and do not require as much study time.

Consider living on campus even if you go to school close to home.
Not only will you miss a lot of things going on, but you may miss out on your first opportunity to live on your own and make your own financial and social decisions.

On the day of your exam, go to the bathroom ahead of time.
This may sound self-explanatory, but there are so many things to remember on test day that it's easy to forget.
