<prompt> Human: Here are all my student loans, the total is 18000 right now. Sorry, dont have the exact number and theres no interest left. So its all principal. Im paying an extra 200 or so per month, should I assign that 200 for the loan with the highest interest? Or should I target the loans with small principal and just pay them off quick?Any thoughts are appreciated.  <response>: Highest interest rate first.
