Child Genius

Nine-year-old Aliyah's psychologist parents have devised a special training regime to give their daughter optimum brain power, deploying everything from juicing to alternative therapies.

Only 15 of the gifted youngsters remain. They face two gruelling rounds: Logic and Reasoning and Memory Recall - where they have just one hour to commit 104 randomly shuffled playing cards to memory.

It's the penultimate stage of the competition, and the stakes are high as the ten do battle for the six places in the final.

It's the final, with six of the UK's most gifted youngsters battling it out, including Rubaiyat, whose chosen specialist subject is string theory, and chess champion Sharon.
