so, i read gretzky's autobiography when i was a kid. i was about ten. that's how i know he didn't go to high school.
he didn't go to high school because he was a child hockey prodigy and he didn't make the time to finish grade school while playing professional hockey, as a child. nowadays, he wouldn't be allowed to do that. further, he states in his book, via his ghost writer, that he regrets not finishing grade school, as it left him unable to do basic tasks for himself, like count how much money he has. his agent ripped him off pretty badly.
gretzky commands a lot of respect on the canadian political right, but the truth is that what is known about his public life experiences suggest he wouldn't be very good at tabling a budget.
it's not even clear if he can count to 92.
