Back in high school a couple of my friends had learning difficulties and didn't read as fast as others so they had trouble keeping up in the regular class so they were put in a different one. This was done with the best intentions but they always ended up in classes with the biggest assholes in the school who had serious issues and made their days a living hell.
For me, the most annoying thing was that students were always lumped together regardless of ability in primary, elementary, and junior high so we learned at the lowest common dominator. High school things finally got better when we could choose advanced, academic, and basic streams (though that obviously wasn't better for my friends mentioned above).
Another thing that annoyed me was the jackasses that gave teachers hell. I think it's awful that someone should have to put up with that kind of abuse for their job because some asshat is a terrible person.
