He has the same IQ as Einstein and Stephen Hawking.

And now six-year-old Sherwyn Sarabi, who became one of Mensa’s youngest members with an IQ of at least 160, is the star of a new book about how to bring up child geniuses.

The impressive abilities of Rastrick Independent School pupil Sherwyn, who is currently studying for a GCSE in maths, are laid bare in ‘Off the Scale! Educating a Profoundly Gifted Child’.

Written by his mum Amanda, the part memoir and part handbook for other parents also talks about how to get the right support for a gifted child, the importance of IQ testing, whether to skip grades and more.

It has been released by an American publisher and can now be bought as a paperback online.

Talking about the book, Amanda, a music teacher who lives with Sherwyn in Barnsley, said: “When I first found out he was gifted I was so confused.

He had been learning fast all his life. By the time he was one he knew the colours, at two he could name all the countries on a map and at four he scored off the scale in his IQ test with Mensa.

“I had to read a lot of books to see how I could help him.

“While doing it I thought why not put all this advice into one book?”

In the book, she talks about the amount of work involved in keeping him fulfilled.

“We do a lot of work together outside of school because school just isn’t enough.

“He wants to be taught and learn because otherwise he gets bored and he used to misbehave when he wasn’t being challenged enough.

“Although maths is his favourite subject, he does well at everything he tries, like music– he’s passed his grade five in piano and grade three in violin already.”

The book’s release follows several news stories about Sherwyn, which thrust him into the limelight from a young age.

But Sherwyn does not appear to be phased.

“I don’t really feel different to everyone else, I just do different work to some of them, which makes me feel happy”, he said.

“There are a few other people like me in my class, though, so I like that.

“I’ve always loved maths.

“I like everything about it, especially algebra.

“It’s hard to explain why I can do it though, it just feels natural.

“But I like to learn everything, it’s my favourite thing to do because it’s really fun.”

He explained how he felt when he was accepted as a Mensa member.

“I don’t remember doing the tests. But I felt really happy when I joined and grown up too.

“I think I’d like to be a mathematician when I grow up but I’m not sure what to do exactly yet.

“I just like feeling tested enough by my teacher and out of school.”

Not just academically keen, Sherwyn has lots of other hobbies.

“I go to speech and drama class after lessons, I like football and musicals.

“I love keeping busy.”
