The final six go head to head in a debating contest, hoping to make it through to the last quick-fire round and the chance to be crowned Child Genius of the Year 2013. Eleven-year-old author and world Scrabble champion Shrinidhi may have mastered the written word, but the spoken word fills her with fear. Will a meeting with her biggest idol, Countdown's Susie Dent, help her confidence? Can maths prodigy Oscar, who got an A* in his GCSE aged seven, find an algorithm that helps win arguments? With his photographic memory, nine-year-old Connor has reached the final with ease. But winning a debate requires him to think on his feet, a skill which doesn't come naturally. Connor's taking on nine-year-old Lara, who has an IQ higher than Einstein. While Rohan's parents believe a triumph in the debate could help win a coveted scholarship to Harrow.
