One of my kids started to play the piano at about 13. By the age of 18, he was playing pieces that were Royal Conservatory grade 10 level, and he was accepted into several universities.
He only had one hour of lessons a week during those 4 years of high school, but usually practiced 2 to 3 hours a day, without any pushing on my part. In some of his lessons he wouldn’t even touch the keyboard, they would just analyze a piece of music or discuss the theory behind it.
In university, the professors sometimes told other students to watch him play. His technique, they said, was not great (he himself admits that playing scales early on would have helped), but his feeling was superb.

I actually had to learn to use a slide rule in high school, in the late 1970s.
