Make sure you have a plan first, lots of sequential courses.

Don't be afraid to get to know your professors. They are just as human as you are. Join clubs and stick around campus; it is a great way to meet some of the many friendly people on campus.

It sounds really lame, but if you can't get a class you want, try waitlisting a morning class. People constantly drop them in the first two weeks, so there's almost always a spot. There have only been two instances where I have not gotten a permission number to add a class I was on the waitlist for, and they were late in the day. ALWAYS READ THE BOOK. Always. And don't forget to do the homework! It will help so much when you're studying for a big test.

Ask questions no matter how redundant it might sound or how small it may seem.

It sounds simple, but make sure to follow the syllabus, attend class, and do your work... If you apply yourself, you'll get more out of your education.
