<p>One of the best things I did in undergrad was take credit for as many AP tests as my school would accept. It meant I got to place out of a lot of the killer freshman courses, and instead take a ton of extra upper-level courses which were more interesting to me. By the time senior year had rolled around I only had one required class left to take, and I was running out of classes within my department. Wound up graduating a semester early and saving a ton of money.</p>
