Edit: Sorry I offended someone! If you were educated in the US and had another experience, I'm not invalidating that. I was in HS a few decades back, and I think they've probably reformed those maps these days
So, your question is different.
But yes, to answer your question, in school we also had global maps that centered the Americas and split Asia so that China was on the left and Europe and Africa was to the right
I think it was split somewhere to the west of India, as I recall. The projection may have been over the US, but Im not positive. It was awhile ago

I was downvoted simply for suggesting another poster who hadn't seen it before, and was it really a thing, do a search so they could see different examples it.
Other people here are downvoted simply for giving their (American) experience, that maps showed the US at the centre.
Is it supposed to be a secret or something?
It's probably something decided by state education boards, so whichever map your state decided was all you saw for twelve years. Leading you to think the entire US had the same.
As an aside, I also had 6 years of American Revolution, all told. Every time we moved, the new district would be starting that unit. So annoying
Although it can seem pettily nationalistic (and probably is to some extent), for quickly illustrating "You Are Here", and the relative positions of other countries to your own, centring maybe makes more sense than having some far away country at the centre.
It seems pretty common/natural in different countries too. I wondered if a 'most accurate map' exists, and found Authagraph:

It's not difficult to find the origin country of the map, Japan.
Edit: perhaps more relevant that I went to private schools, so we wouldn’t necessarily have had the same materials as were chosen by the state.
Now there's a map printing shop idea, centering the map on any country you choose.

(I quite like that map, actually.)
But GMT is still Eurocentric and unimportant from the perspective of an individual looking at a map, I do wonder if that will ever change?
(And if you're into science fiction, you've likely internalized the American view of Earth from space without even realizing it.)
I'm not passing judgement here - just saying that cultural influence isn't equal.
