My high school son has one teacher who has admitted to being very OCD. I told him for heavens sake learn her system(s) of doing things perfectly. The woman luckily is very entertaining so I think he will want to please her (English teacher).

She had a funny story that all the teachers were getting moved around over the summer and she was waking up from nightmares about what if her blue organizational systems didn't match her new room? Was she going to paint? Was she going to have to buy all new stuff? That is what was keeping her up at night. Luckily her new room coordinates with her lovely blue storage boxes.

But yes learning 7 different ways of doing things can be overwhelming.
