<prompt> Human: Im going to be getting a full time job soon that will cover all my expenses, making my income from my retail job extra income. I plan to throw that money straight into my student loans. Should I put it towards my federal loans which I owe more on due to my payment plan or my private loans? Or divide the extra money between the two? Or does it not really make a difference?  <response>: Whichever one has the highest interest rate is the best choice financially.
