Isla McNabb, a 2-year-old toddler from Oldham County was accepted as the youngest member of the society ever after scoring 99th percentile on her IQ test. This cute little bubbly toddler has just begun her journey. There have been many young children in the past who have amazed the world with their high level IQ. Here we are presenting a small list of high IQ children who will blow your mind with their achievements at a very young age.

    This list needs to be regularly updated because there’s a 5-year old boy in Ghana by the name of Jeremiah Owura Addo and he started performing mental feats at the age of 3 years. Currently, he is at the beginner level of learning 12 world languages and is able to mentally compute the product of 2 and 3-digit numbers in a few seconds. I will send you YouTube links to follow up on this child prodigy. You can contact me for personal details regarding this boy if you are interested.

    Does anyone remember Somerset Hughes, a little girl in London UK in the early 1960s with an exceptionally high IQ?
    Quite often in the news at that time – what happened to her? What career did she follow?


    Greetings of the Day.

    I would be happy to let you know that my daughter (4 years old) has skills like reading English and talking in English.
    We belong to India and our mother tongue is “Marathi” and ”Hindi”. At home, we mostly talk in Marathi/Hindi.
    We observed my daughter started speaking in English when she was 2 years old and to date, she is talking in English language only.

    We seek your advice to enhance her natural talent and make her a genius.

    We are presently living in Kuwait.
