If you are applying for FAFSA you should know about certain guidelines before you apply for it. You must submit the MPN with the application when you are going to renew the application. MPN refers to the master promissory note which is an officially compulsory document where all your signature agreements to reimburse the loan amount under Federal District Student Loan Program. If the student fails to repay the amount then the authority can sue him by using the MPN.
