Sacred Haven of Debauchery

Oh, no, Imaris, it wasn't me, keep looking ;)
School, school, I love my class...
First, I was in school A, then in school B, then back to A in a third school. The coolest one. They even let me stay ;)
And we have... A - physics and math, B - chemistry and biology, C - computer science, D - a bunch of losers. That's where all the trouble happens ;) Someone got pregnant, someone got stabbed, someone committed suicide, oh, mothers...
