Liz's class in school is a kind of weird class as it's mostly known by the nickname "Rindleader class", a class filled with female troublemakers. Although that alone isn't really that weird, it's the fact that they are either from higher class households, girls that are used to being able to get anything they want with any means necessairy, or poorer households, girls that would do anything to get anything they want. Liz fell kind of into the former category. For certain reasons only female teachers are assigned to this class.
