Drivinglessons

This Tursday I will be doing my first drivingsexam. I'm already pretty nervous about it :s.
I really hope that I pass but I still make somethimes some mistakes. Like not looking good or I change the gear too late. I know that nobody can drive perfect but still.. My twinsister is also going to take het drivingsexam at the same day which also makes the pressure to pass bigger.
