Oh my god, time flies. I can't believe you're college-aged now, RE!

Definitely avoid 8 am classes, as Hannah said. And, although it is important to do well in school, your grades in college absolutely do not mean everything. More important are the experiences you gain, such as an internship or job connections, that put you in a good position out of college. But this is from someone who went into work straight out of college rather than grad school, since I really didn't have a desire for it.
