I didn't return my financial aid letter in time and it's been revoked. Please help!?

Call first and follow up with the email. It is very important to enlist the financial aid counselors interest in you as a person, so it behooves you to explain why you neglected to get the paper back in time. Tell them why or what you were doing that had you distracted. If you were working or had unusual family obligations or some big living condition problem, all of those are justifications that help make a case for the showing leniency and bending the rules. Sure it's making an excuse and all that, but you are making an appeal. It's like a court proceeding. You have to present a case for yourself.
