someone correct me if i'm wrong. In my experience, the only way to change your score quickly is with a rapid rescore. The only people Ive ever seen with the ability to do this is a mortgage broker, or someone with the ability to pull all 3 reports. Rapid Rescore last I heard was about $30 per item per report. do a google search and see if anyone else provides the service besides a mortgage broker, Ive done it and didnt find anything good.
Whats the rate on your student loans? I thought student loans were naturally extremely low. If so, maybe you can call them and restructure the payment and use the extra money to make your improved credit into even better credit. I know dept. of ed. is easy to work with. (or you could go back to school, payments stop until 6 months after graduation

j/k
Best of luck,
