Elon Musk's mother Maye Musk took to Twitter to post a photo of an aptitude test the Tesla CEO took at 17. She said that the SpaceX founder had to be retested for the computer programming aptitude test because the examiners had not seen such a high score before.

The proud mother said, " @elonmusk 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. #ProudMom."

The tweet featured a photo of a letter from the Office of the Director of Information Management at the University of Pretoria in South Africa dated May 17, 1989. It says, "I have requested ISM (SA) to conduct aptitude tests on ELON MUSK, regarding the computer programming etc. The results were outstanding." It showed that Musk scored A+ in both operating and programming.

Elon Musk attended the University of Pretoria in South Africa briefly before he moved to Canada.

The tweet has since received 154.2k likes and been retweeted 11.9k times.
