It's mock test day and the pressure is on for our celebrity learners to show whether they've been paying attention this week. They swap instructors and sit the test under strict exam conditions. Made in Chelsea's Francis Boulle has a disastrous mock test and nearly runs over a pedestrian, making instructor Pells worry about how much work he's got left to do. Things don't get much better when Francis' girlfriend Katie and best mate Ben arrive to act as back-seat drivers, and he has several more near-misses with them in the back. Former Pussycat Doll Kimberly Wyatt passes her mock, but Olympic gymnast Claudia Fragapane just can't get over her nerves, let alone remember which side of the road to drive on, and is missing instructor Ricky's Zen-like relaxation techniques.
