A little boy who can count up to 200 and name every country in the world has become one of the youngest members of Mensa.
Sherwyn Sarabi, aged three, from Barnsley, South Yorkshire, is ranked in the top 1% of the most intelligent people in the world after tests revealed he had an IQ of 136.
His mother, Amanda Sarabi, said she was really proud of her gifted son, who she describes as "amazing".
Sherwyn, who has a reading age of six, began speaking at the age of 10 months and was talking in sentences at 20 months.
By the age of two, Sherwyn could read, recognise and name countries, flags, planets in the solar system, parts of the body and internal organs.
Mrs Sarabi, 36, a former teacher, said her son could point out every country in the world on a globe and match it to its flag. He could also explain the function of each internal organ.
"His general knowledge is amazing. He knows about everything. It's not like talking to a three-year-old. He doesn't even watch children's programmes, he watches the news," she said. "The weather is his favourite, especially the world weather. He loves that."
She added: "We take every day as it comes. I've never forced teaching anything on to him. If he comes to me and asks me about a topic, I teach him to the best of my knowledge. Sometimes I have to look it up because I don't know the answer but I explain it to him, then he's happy."
Mrs Sarabi said she and her husband, Davoud, 37, who was studying construction management until he was involved in an accident, were well-educated but "nothing extraordinary".
She said they first noticed Sherwyn's interest in learning when he was 18-months-old but his intelligence seemed normal to them until other people pointed out how unusual it was.
After his third birthday, Sherwyn was tested on the Wechsler Pre-School and Primary Scale of Intelligence, which placed him in the 99th percentile with an IQ of 136. The normal range using this test is between 85 and 115, with the average IQ being 100.
The high-IQ society Mensa has only 100 members aged under 10 out of 22,000 members across Britain.
John Stevenage, chief executive of British Mensa, said he was pleased to welcome Sherwyn to the society.
"As a bright child with great potential we hope he will thrive with the Mensa network as support."
