Scholarship rescinded, how to make an appeal?

I am glad that you did the right thing and found out now instead of saying nothing, enrolling and have National Merit inform your school that you are not a candidate for this years scholarship (leaving you in more trouble; misrepresentation and possibly having not only the scholarship, but your admission rescinded).

While I feel for OP, and I am glad that s/he is now better. unfortunately s/he is not eligible for a national merit scholarship.

For OP the national merit door closed, when s/he did not enroll in college Fall 2013 after graduation. I would definitely recommend finding out if there are other scholarships, that OP would be eligible to receive.
