I joined the ROTC to cover my room and board at first.
If any of your friends are going to the same school, you could think about finding an apartment near campus. Its convenient to have everything taken care of in the dorms, but it's expensive. And roomchecks and that kind of shit suck.
With a few of your homeboys, any place that has a pool and a spot for your grill is a "cool apartment." Also, all the girls want to kick it off campus, so the apartment is a huge advantage.
Waiting tables is a pretty classic college job.
