<prompt> Human: So I have a total of 37,935.019 in student loans. I am trying to pay them off as fast as possible obviously. I pay slightly more than the minimum but at 500 a month its hard to pay any more. As of 8 months ago I had a 781 credit score.I just want to know if there is a way to get more efficient with paying these off. 3 are Federal Loans and 2 are from Sallie Mae.The loans are as follows:University Accounting Services: 8,059.98 at 5.
