Greg James and Bella Mackie didn’t pay much attention at school. So they’re asking Britain’s most inspiring teachers to show them what they missed in this series of fascinating and fun lessons. This week it's psychology with Mrs Harrowell, who explains how memory works to Greg and Bella - demonstrating her points by testing their recollections of everyday objects and iconic film quotes, and teaching them a dance that means they'll never forget the name of a part of the brain they'd never heard of before this lesson. Bad students of all ages are welcome. Expect brilliant teachers, captivating subjects but absolutely no homework.
