Classes often with the same teacher different period. High school it was harder but by their senior year they had almost identical classes and teachers just differnt periods of the day. Made homework so much easier for them, they didn’t cheat but they is get caught turning in the same paper on their dog one time I think as freshman. The teacher called them both in and said why is the report the same, and they both looked at him and said well it’s because it’s the same dog. They both got an A.
