15 and my handwriting is next to unreadable in exams?

A lot of really intelligent people have horrible hand writing. I once had an education professor whose handwriting was so bad she had to fill out paperwork to get a computer to type everything in her doctorate cles. My suggestion to you is to talk to someone about getting an IEP (individualized Education Plan) to get yourself access to a keyboard during tests. It's really unfair that your grades should suffer just because your hand writing is poor.
