Go to Vanderbilt.
Think about your long term prospects. If you ever go into management/adminstration, the brand-name will help immensely.
If you still need some reassurance, think about it as possibly giving you a starting salary of $300 more per month as compared to a OSU degree. You'll get your Return on Investment back in just 100 months.
Work as TA and do research on your weekends/late nights.
And don't forget about your classes too.
Don't you want to graduate ASAP? Of course some sacrifice (sleep time/social life/vacation) is required.
If you can transfer some credits, it'll help.
