I am hoping that if you got into Yale that you know that it is legal to go to school and work. If you are not just spamming, I would not worry about reducing your loans I would try to find more income to pay off the loans. Try going to
www.companyexpert.com and
Outsourcing to Freelance Programmers, Web & Logo Designers, Writers, Illustrators on Elance and post your credentials perhaps you will get some projects that will help you earn some money. Good luck.
