A six-year-old whizzkid has set his sights on emulating Bill Gates - after becoming the youngest person in the world to master Microsoft Office.
While other children his age use their computers for playing games, Humza Shahzad has been training for a professional exams qualification usually sat by adults.
His parents taught him to use his first laptop at the age of just two.
After mastering Microsoft Word and passing a test on the programme last month, Humza now hopes sit the next six exams to earn the Microsoft Office Specialist qualification.
His dad Asim, 40, of Engadine Close, Addiscombe, said: "I didn't want him to waste his mind on things like video games. I thought, why shouldn't I get him involved in something different.
"I'm an IT consultant so I thought I'd get him involved in computing. He was too young to learn programming, so I did some investigation and found what programmes might be best for him to learn at this age.
"The way he learns to do different things, you would be amazed.
"His teachers at school call him a superstar. They say he never misses even a single detail and works so hard."
Humza, a Year One pupil at Ark Oval Primary Academy in Cherry Orchard Road, said he was "ecstatic" to have passed his first exam.
And he now has ambitious hopes for the future. He said: "I'd like to do something different like Bill Gates. I want to make new games for children."
Humza's parents Seemab and Asim bought him his first laptop when he was two
Humza's technology expertise have also come in handy at home, where he has helped mum Seemab, 36.
Mr Shahzad said: "My wife was not aware how to use the dishwasher, so Hamza, who had just turned six, opened his laptop and went to Google.
"He had a look at the model of the dishwasher, found it on Google and kept watching the video of how to use it. Then he came back to his mother and told how this is how the machine can be used."
Humza sat the Powerpoint exam at Best Training in Streatham last week and will attempt the Excel test next.
Steve Herbert, who runs the centre, said: "It is normally something adults do if they want to progress their careers. It is very impressive."
