Martha and Ollie throw Cassie and Maxwell off the maths team, desperate not to be outshone as they were last year by the lightning-fast buzzer technique of the younger pair. Outraged, Cassie and Maxwell vow to fight for their rightful places on the team. After what he considers a near-death experience stranded up a ladder, Alfie is determined to compile and complete a 'bucket list' before it's too late. Jas thinks she's helping him by encouraging him to do the scariest things she can think of, but poor Alfie becomes increasingly traumatised. Meanwhile, Rob has to attend a History Catch Up Club run by Mr Malone. Lily is frustrated, as she's hardly getting to see Rob at all and Ms Parfitt is jealous of the Club's popularity.
