Not bad, but some flaws in logic. (Like how are they expecting me to believe that a 14 year old girl - or anyone else in that hall for that matter - can spend at least half a day without having to pee? And how could a single girl keep control of a situation for that long without any help? A single girl? Not being overpowered by dozens of adults?) Also it makes me wonder wether Cardassia is only existing, so that authors don't always have to use the Mirrorverse if they want to write about dystopian-level scheming.
