A FOUR-YEAR-OLD child genius has become the youngest member of an exclusive high IQ society.

Sherwyn Sarabi, of Eastend Crescent, Royston, has an IQ over 160 and is already a member of Mensa.

However, his latest achievement of joining HELLIQ is even more impressive given their stringent entry requirements.

Sherwyn - who was able to identify every country on the globe aged two - received his certificate of entry last week and features on the organisation's website.

The young lad now finds himself among its 'profoundly gifted' 85-strong membership.

Proud mum Amanda said: "Sherwyn keeps on getting even higher recognition for his abilities. He still keeps giving us a shock!"
