Private loan for school?

I need money for a school loan now. I found out two months ago that there was an error on my credit report which dropped my otherwise perfect credit down. I got the problem resolved an the error has been taken off my report but my credit score has not returned to what it once was and they told me that once they deleted the error my credit report and score would return to what it was. It is now July and I need to apply for a private student loan in which the check comes to me so that I may pay for my living expenses and tuition over the course of the year. And since my credit score is now sitting at 637 down from 712. I get pre-approved for loans on the condition of having a credit worthy co-signer and unfortunately the people around me don't have good credit, I'm the only one and no one will help me. Without this money I can't go to school and I'm in my senior year. I don't know what to do. Does anyone know any solutions? Creditors I can borrow loans from?
