So your budget is c~$30K/year for tuition, room and board: $25 from your parents & $5-7 that you can borrow. You can probably earn another $3-5K over the summer after senior year to cover first year spending money, but be aware that If you are going a polisci direction you will want to get summer internships, and they are typically badly paid or stipended.
So, CC: where should a go-getter, highflier student with a 4.0UW / 34 ACT / 1520 SAT / likely NMF look for a non-southern, preferably urban college that will come in under $35K/year?!
