I always hated school back then, because the lesson-plans were never "right" for me, I'm somewhat ADD so the average/normal "robotic" teaching was like drilling my brain with a dull screwdriver. My favorite class was always literature because it was always somehow more unique compared to other classes, diving through different time periods, different genres, etc... as I got older I did somewhat miss the social aspect of school though, things were a lot less easygoing when everyone is young and you can just hang out (though maybe it's just me since I never really stayed in touch with anyone from school)
Another bad thing about it is the common bullying, that has been an issue for how many hundreds of years I wonder, when some people find themselves to be vastly superior over others yet they grow up to be the trash of society. (Worst part is when they target someone that isn't strong, someone that takes that experience and gets completely CRUSHED by it, and doesn't grow up living their full potential, instead the bully takes the victim with him to the bottom)
Well those are my 2 cents. Hope that helps!
