I don't know if it's different for tests..but I took drivers ed, and one girl forgot her permit one day, and the instructor was really annoyed. She was going to make her pay or something and I don't knwo if she would be able to drive...however, that's drivers ed. It's probably different. I'd imagen you would need it? Could you call first thing tomorrow and maybe get a new one and/or make a new time for your test???

Goodluck, btw You'll do great
