School where all the kids are separated. The social groups are all distinctly separated. The different groups often never interact with each other ever. Oftentimes, this leads to a socially fucked atmosphere at school. There are also many 'fake' kids in these poser schools. They will claim to be someone's friend and then talk shit about them without them knowing. It escalates to a point where most people at the school talk shit behind other people's backs.
