I went to one week of school last summer for Sat air driving. Was in a group of regular wanna be drivers. We never did take a written test. As we practiced driving they asked us to recite the commentary and seeing habits but never was there a test. I believe we all passed but he made notes about all of us needing to become more familiar with the vehicles.
They will give you hints to memorize the commentary and seeing habits and that makes it easier. You'll be fine. Relax, have fun and best of luck.
Oh, be careful about going out drinking with your new driver buddies. Makes you feel like crap the next day and turns practice driving into a real rush. dw
