My kid is a very young 2022. He uses his age as fuel to work harder. The college coaches he interacted with did not care about his age. There was a microsecond consideration to repeat 8th grade on his part, but once he was accepted to his preferred HS, that was a dead issue (mom would not have allowed him to repeat 8th grade). From a purely selfish perspective, my wife is annoyed he won't be able to drive himself to HS school, so she is his morning uber as it is on the way to her work.
