A three-year-old boy who can count to 200 and name every country in the world has become one of the youngest members of Mensa.

Sherwyn Sarabi, from Barnsley, South Yorkshire, is ranked among the top 1 per cent of cleverest 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 described 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, he could read, count to 200, 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.

She said: “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. 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.”
