Take public transit like 90% of other college students. You'll save on buying a car right away, and one thing you missed that will analy rape you: car insurance. When I got a quote to put my car insurance under my name it was over 5k per year.
Make sure to have a summer job lined up so you can be working full time between terms, that way you can pickup money for the next term. At that point you can be living at home instead of spending all that money on rent.
I got lucky with the fact that the college was in my city so I stayed home. My only real expense was tuition and books, and yeah, books will rape you. If you have a choice to not buy a bood, then don't, and see if you actually need it. I had some courses where the books were only opened once, and it was to put my name in it. A huge waste. Ended up in the recycling bin. College books are outdated a year later.
For food, a large pizza costs about 20 bucks and should last you a few days. 😉 Kraft dinner is really cheap too.
