I went to a tiny mixed age school and basically each kid worked on workbooks at their own pace.
The older kids helped out the younger ones and the teacher walked around the class and talked to each kid to help them along with thier work if they got stuck.
There wasn’t any lecture style teaching with the teacher explaining concepts to the whole class at once.
We all worked on one subject at a time, but we were all at different points in it.
When my family moved and I left that school I was multiple years ahead of where I was supposed to be in several subjects and normal school was very boring after that.
