The search for the UK's best quizzer continues, as 10 of the 14 remaining contenders are put through their paces by Jamie Theakston, Kate Garraway, Myleene Klass and William G Stewart. Rounds including Only the Strong Survive and Brain Chain see one of the contenders through to the final round. The finalist then selects another contestant to go head-to-head with in Do or Die. The winner earns a guaranteed place in the Grand Final but the loser is out of the contest for good.
