I haven't backread, so there may be some repeats here. But I am a current college student so here's some things I have learned.
buy the mealplan if you're on campus. you probably won't have a stove in your dorm room, so that makes it tough to eat decent. off campus apartment, probably will have a stove, but most kids don't live off campus first 1-2 years.
walk to class, or ride a bike, cars mean parking passes and gas.
learn to drink cheap booze.
find out which bars have the best specials.
it's hard when everyone else is doing it, but do your best not to order out all the time.
if you do have a car, don't ignore parking rules, although they are usually ridiculous (i paid so much money on parking tickets my first couple years)
don't not spend money at the expense of being anti-social, but don't be a cheap skate and not go out, in the end the memories are worth it and as long as you don't go overboard, get decent grades, you'll be ok
