I'm really good at English... which is why I also hated those classes in school, they were boring.

But the worst class I've ever taken is probably one called "Life Skills" in middle school, which felt like a bunch of mindless, kindergarten level exercises with no real curriculum. I'm pretty sure they put me in it because they assumed my autism diagnosis meant I needed the same help as people with learning disabilities that put them several grades behind and still unable to understand basic arithmetic.
