I would see them devided by age. The smallest kids, 1 to 5 are in one class with one teacher. 5 to 10 and 10 to 15. In the classes the teavher just teaches, the older kids get a subject and then the teacher gives a subject to the younger ones. It’s not perfect, but it works

No really, no. As long as the character is a good addition to the story.
