Today is the dreaded mock test and after just four days on the road, our celebs are panicking that they're not ready. Tattoo Fixers' Sketch performs well in his test until the last minute. He gets really depressed when he finds out he's failed and threatens not to turn up to the real test. Nathan cracks under the pressure and fails his mock too. His boyfriend and best mate come along as back-seat drivers but he shouts at them to get out the car when it all gets too much. Vicky, who has struggled all week, also fails her mock and cries at the end of it. Things pick up for Vicky during the Speedway Race Track Challenge where the celebs have to prove they can maintain a consistent speed. She is announced joint winner with Sketch, leaving Nathan to come last. However, at the end of the challenge Vicky has an important announcement to make.
