this is wrong info, or at least your friend was feeding you a bunch of bullshit.
He showed me the invoice of it because I couldn't believe it myself. He took 4 and 1/2 years to graduate and did not pay on it. Also why do I hear people always whine about still owing on student loans. Do they defer or get forbearances for time after they graduate too? Interest has got to be stacking up on people who said they haven't paid for their student loans 4 years after graduating.
