If you are a provisional senior (an "11th" grader who entered high school in the fall of 2005) and you are trying to graduate at the end of this year, you should have signed one. The counselors were outside of the cafeteria for four days last month and we have been in our offices ever since! With or without your signature, your credit check was mailed home (and we kept a copy, so don't try to pull any tricks). :)
