Elon Musk's mother, Maye Musk, took to Twitter on Wednesday to share the result of a computer aptitude test that the billionaire entrepreneur took when he was a teenager. She revealed that the Tesla CEO had to be retested because examiners had never seen such a high score before.
The picture shared by Maye Musk shows a letter signed by the Director of Information Management at the University of Pretoria in South Africa, which Elon Musk briefly attended before moving to Canada at the age of 17.
The letter, dated 1989, reads: "I have requested ISM (SA) to conduct aptitude tests on Elon Musk regarding computer programming etc. The results were outstanding."
It goes on to show that Mr Musk scored an A+ in both Operating and Programming.
Sharing the letter on Twitter, Elon Musk's mother wrote: "I found your computer aptitude test from when you were 17. If I remember correctly, they had to retest you because they had never seen such a high score.
"No wonder you are such a brilliant engineer," the proud mum added.
The tweet has racked up over 27,000 'likes' and hundreds of comments on the microblogging platform.
Maye Musk often shares throwback pictures of her son on social media.
