Fwiw, AP Computer Science must have gotten better.

I took AP Computer Science in High School in 2012. The whole curriculum was based on this “Grid World” Java program where a Grasshopper extends JumpingBug extends Bug or something like that, no not as an analogy for OO, the classes were literally named like this. And, the AP test asked specific questions about Grid World's implementation, so you had to learn about it even if you understood the underlying computer science concepts.

I wish we learned about linked lists. I didn’t get that until college.
