What is/was your hell in school?

This is strictly academic, I really don't feel like talking about all the crazy nonsensical shits that happen in the junk of a place that is HS, had many horrible experiences (like I vaguely mentioned drug and sex scandals), though few good and memorable stuffs too...

Edit:

Btw I assumed you were talking about High School only. Well Elementary School and Middle School ere all good to me, little innocent me, surrounded by friends playing around, getting rewards doing my home works right, being motivated, looking for a bright future, having my first kiss at 2nd grade and her being the one to tell me she liked me..., memorable times idolizing my favorite football hero Romario (Brazil) and scoring goals after goals in my shcool soccer games. I had many bad childhood experiences but those were not at school (school was rather safe heaven from bad stuffs that had happened). Until High School I actually loved school.
