ok, and could you give me more information about what is a Master Note?
The Master Promissory Note MPN is a legal document that promises to pay your loan and accrued interest and fees to the U.S. Department of Education.
and could I receive more than one loan?
You may receive more than one loan under an MPN over a period of up to 10 years to pay for your or your child's educational costs, provided the school is authorized to use the MPN in this manner and chooses to do so. The school will inform you what loans, if any, you are eligible to receive.
