Martha and Ollie throw Cassie and Maxwell off the maths team, desperate not to be outshone as they were last year. After what he considers a near-death experience, Alfie is determined to compile and complete a 'bucket list'.
Mrs Griggs launches a mentoring scheme and Maxwell picks Ollie. At first Ollie is flattered, but he soon becomes fed up with Maxwell beating him at chess.
