The bakers return to school, starting off with the classic canteen favourite, flapjacks, before being tested with a fondly remembered school cake technical, with a catch. For their final exam, they have to produce a spectacular school fete showstopper, full of nostalgic treats. Mr Hollywood and Ms Leith judge their efforts, before deciding which of the students to expel.

Noel Fielding and Alison Hammond lead the bakers through pastry week, where they make savoury plaits in the signature challenge before attempting a traditional gala pie in the technical. Finally, their skills are pushed to the limit with an intricately sculpted tart showstopper. Whose plaits will leave Paul Hollywood and Prue Leith tongue-tied? And whose pie will equal goodbye?
