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.
Matrix: Revolutions. I didn’t even see the fourth one.
