At three years old, Mikhail can add in the thousands. At six, Adam is able to solve quadratic equations and is studying A-level chemistry. By five, Michael (now aged 11) was reading Shakespeare and learning Hebrew. Feats like this are staggering. But what makes such an exceptional child? Are they born this way or can parental upbringing have a significant impact on a child's development? For some, having gifted offspring is a dream come true: a promise of wealth and status. For others it's a living nightmare as they struggle to handle the repercussions of their prodigy's superpowers. What will become of these special children?
The first episode of this two-part series catches up with the programme's youngest prodigies. Peter, at 11, is England's under-12s chess champion; Adam, now eight and a half, is heading off to a prestigious boarding school; and Mikhail, now five and a half, is a maths prodigy turned spelling star. And a new Child Genius is introduced: three-year-old Georgia. When Georgia was two and three-quarters, she became Britain's youngest member of Mensa. Her mother Lucy is so desperate for Georgia to get into a nearby school that she had her IQ tested to try and get her in. But will Georgia's gift win her a place?
In the second episode of this two-part series, viewers catch up with the programme's now 13-year-old prodigies. Aimee practices piano seven days a week and her star is rising, including a win at a prestigious competition. But the pressures of high-flying mixed with teenage hormones tests her relationship with her parents. Michael is writing his fourth novel and is now home-schooled so he can pursue his academic interests in Ancient Greek, particle physics and even Anglo-Saxon. But how will he negotiate the transition from child prodigy to becoming a man? Dante and his parents have tried a string of therapists in search for answers as to why his gift is so troublesome for the family. Dante has a strong interest in neuroscience so undergoes an MRI scan to try and explain why his intelligence makes him - and his family - unhappy. And in an interesting twist, Dante and Michael have become friends: but what happens when two teenage geniuses get together? Will Dante get himself into trouble for taking a replica pistol into school after his trip to Paris?
This edition meets an eight year old dubbed `the next Picasso', and reveals what happens when a genius child grows into a clever teenager. Child Genius introduces a new generation of gifted kids, including Kieron Williamson, an eight year old with an amazing ability to paint. The film follows Kieron and his family in the run up to his third commercial exhibition in his home village of Holt in Norfolk, where in just half an hour he sells £150,000 worth of paintings. What will his parents do with Kieron's extraordinary talent, and his unprecedented earnings? This film also catches up with chess genius Peter Williams, now 14, and piano prodigy Aimee Kwan, now 15. Are they still far ahead of their peers, and do they resent the 'genius' tag? There's nothing average about these children and their lives are a constant round of competitions and contests. But whose decision is it to put them through all this, and were these children born brilliant or are they the product of pushy parents? The children speak frankly about the mixed blessing of their talents and the opportunities as well as the heartache they can bring. Does having an extraordinary mind define them? Are they alienated from their peers or have they learnt to relate to children their own age in order to have a normal childhood? And as for the parents, is having a child labelled as gifted hugely rewarding, or do they feel pressure to support their prodigy's talents and their thirst for knowledge?
Earlier this year, 21 highly gifted children aged seven to 11 were selected to take part in a competition run in association with British Mensa, to find the UK's ultimate child genius. Alongside their home lives, the series charts the progress of some of these extraordinary children through the course of the competition. There is eight-year-old Josh, a chess prodigy whose mum Hilary has a grand plan to put 10,000 hours into making him a grandmaster by the age of 13. Ten-year-old Hugo is an outspoken trainspotter who gets frustrated by those who aren't as clever as him. And there is also Shrinidhi, the current World U-12 Scrabble champion, whose passion for words and all things literary extends to her favourite treat, which is sniffing old books.
Mild-mannered nine-year-old maths machine Oscar, who became the youngest person ever to get an A* in GCSE Maths aged seven, is a competition favourite but, away from the familiarity of maths, how will he fare in the unknown territory of this week's general knowledge round? Eleven-year-old Seyonne is one of seven from a family of high achievers, whose mum Maria expects her daughter to make the best of her education - something she herself failed to do. Meanwhile, 10-year-old engineering enthusiast Hugo believes he has enough raw intelligence to breeze through this week's competition, but his confident personality is starting to upset some of his rivals. Eleven-year-old Leonard Ravi Shankar Buckley has the vocabulary of an 18-year-old, but his tendency for theatrics often means he loses focus at the crucial moment. And human abacus Rosa Maria may be faster than a calculator at maths, but with her study regime in tatters on the big day will she be able to overcome her nerves?
It's the Spelling Bee round in the child genius competition. Has rebellious Hugo's lack of effort finally caught him out? Will human dictionary Ben's love of long words help him sail through, or has he met his match with Scrabble champion Shrinidhi? Aged nine, Connor is the youngest contender still in the competition. Despite intending to take his maths GCSE while still in primary school, he's less confident when faced with mind-boggling spellings such as triskaidekaphobia, extemporaneous or even ovoviviparous! But single mum Sarah is determined to get him through. Sibling rivals Catherine and Matthew entered the competition together, but with Matthew a surprise exit in the first round, it's big sister Catherine's chance to show her mum she's just as bright as her brother. And 10-year old Longyin is on a school trip to Dartmoor, but will his first time away from dad Terence affect his meticulously planned study schedule and ruin his success in the competition?
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.
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. Eleven-year-old Rubaiyat already has an A* at Maths GCSE, but is hoping the competition will help him add another feather to his cap. Eight-year-old Tudor's perfectionism and his parents' expectations make him a determined contender. Will the competition challenge piano prodigy Curtis, who has already completed the first year of a university degree, at just nine? There's also eight-year-old Jocelyn, who has one of the highest IQs in the competition, but has not been to school for more than half a day.
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. Eleven-year-old Eleanor is an avid reader who entered the competition without her parents' knowledge and her mum Catherine worries about the pressure her daughter is under. How will the latest rounds test sibling rivals Tudor and Hazelle? Do nine-year-old Aliyah's psychologist parents still have the winning formula? And can can musical prodigy Curtis handle the pressure of his mum's PR campaign to promote his genius?
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. They face two challenging rounds: Spelling, a gruelling test of some of the hardest words in the English language; and General Knowledge, where they must answer questions on a vast range of topics from astronomy to geography. Eleven-year old Sophie is an A-star student from Essex, whose dinner lady mum takes a relaxed approach to her child's brilliance. Cuneyd is a 12-year-old science prodigy from London who was diagnosed with Asperger's syndrome when he six. Can 11-year-old Eleanor hold it together long enough to get through to the final, and will eight-year-old Tudor's many hours of supervised preparation be enough to guarantee him a place?
It's the final and just six of some of the UK's most gifted youngsters remain. Eleven-year-old Rubaiyat's chosen subject is particle physics. Chess champion Sharon has chosen the Battle of Stamford Bridge. History enthusiast Eleanor has chosen Queen Victoria's childhood. Tudor has taken on the alkaline metals of the periodic table. Also taking part is Rayyan, who is only seven, and ten-year-old Ria, whose mother Manju has been prepping her all the way.

It's day one, round one of the competition, and the children display a phenomenal array of linguistic skills, tasked with spelling some of the most complicated words in the English dictionary. For round two, they must master Old English, a language so difficult it's normally learnt only by academics. As the competitors take to the podium, it's their first taste of performing live in front of the Child Genius audience. The heat is on as the children vie to avoid elimination.
Today it's all about maths, as the competitors demonstrate extraordinary feats of written and mental arithmetic. There's additional twist to the first round of the day, as the competitor with the highest score will get a fast pass straight through to day 3, avoiding the day's challenging second round. The remaining 15 will have to take on one of the most complex recall rounds yet - memorising information relating to companies, sectors and share prices from FTSE 100 companies, as well as having to do complex calculations with the data.
For the third day of Child Genius the 14 remaining competitors take on geography. With questions in the morning round covering 4.5 billion years of our planet's history, the nerves are really kicking in. And the stakes couldn't be higher as the competitor with the lowest score will face immediate elimination. In the afternoon the remaining competitors take on a challenging memory round in which they must memorise a sequence from a pack of 100 randomly shuffled cards, each with an image of a different world flag. At the end of that round, a further two competitors will be knocked out.

In the morning the competitors must demonstrate an extraordinary range of knowledge about some of the world's most complex scientific principles.
The semi-final of the Child Genius competition. Nearly half of the eight remaining competitors will be knocked out today, as only five can make it through to tomorrow's final. To make matters worse, illness threatens to derail one competitor and nerves nearly send another crashing out. Quizmaster extraordinaire Richard Osman presides over today's gruelling language rounds. In the first round, the competitors face fiendishly difficult definitions and anagrams, as their understanding of the English language is stretched to its limit. In the afternoon it's sudden death spelling, where one false move could send even the morning's top scorer home.
The child geniuses tackle their specialist rounds, including epidemiology and cryptoanalysis. The last two then go head to head in a quick-fire round. Who will claim the trophy?
