I actually got this one right when I started at CU.
Get to the book store and pick up either a pocket calendar planner or a palm PDA. Professors and TAs do not like when students forget to turn something in on time because the student simply forgot. This means that they have to bend the rules established in the syllabus and give you an unfair advantage.
If you get super adventurous you can even try out this cool looking Mac app called Schoolhouse.
