A spokesman for Mensa said: "I can confirm Niraj Kumar scored 160 on the Cattell III B IQ test which makes him eligible to join Mensa."
Delighted at the news, Niraj Kumar told the local media in Birmingham: "I was really happy when I found out I had been accepted. It is a great honour. I enjoy school and my favourite lesson is maths. I want to go to Oxford University but I haven't decided what to study yet."
Son of Sandeep and Sejal who own the Lichfield Road news shop in Aston, Niraj showed rare brilliance since his early years.
His mother, Sejal, said he would help out in the shop often: "You couldn't stop him helping. He used to hand over the change to customers and everything. He has always been very bright since he was very young. I always thought he was special but I didn't know just how much."
