<p>In the UC system, a “supplement” in the application review process has nothing to do with money or disability services and no documentation is required. The student has the opportunity to provide further clarification on whatever it is that a reader noted in his/her application that would merit further review. It absolutely can “get a student in” without any verification. I would advise you to talk to the head counselor at your school and have that person take it from there. As others have said, it may be a legit disability, or it may be a very dishonest way to gain admission to a university.</p>
