A lot of people point out that it doesn’t make any sense that Harry and Ron didn’t like their schoolwork. Well I figured out why:
It’s because the magic system is just as boring in-universe as out of universe. It doesn’t make any sense in universe either. Harry and Ron realised Rowling’s magic system kinda stinks way before we did, because they spent all day learning it.
If Sanderson had been writing Harry Potter, then Harry and Ron would have liked learning magic as much as Hermione did (Also, Sanderson actually DID write a book about a super-school, it’s called Skyward, it’s good)
I’m currently going though the books and from what I can tell, Harry especially takes issues with some teachers. He hates history and doesn’t understand divination but he’s fine with charms, defense against the dark arts and even potions once Snape no longer teaches it.
It’s just that during the lessons she describes, they usually have stuff like Quidditch or Voldemort stuff going on so they don’t really pay attention. They also don’t like doing homework so they let Hermione do it for them. And they still did pretty well on the OWLs so all in all, I think they were fine with class but by and large, she just doesn’t really write about classes that went their regular course.
