Yeah. It sounds like Finland is mostly the same as the US. Here you get different classmates each year, but you’re together all year and often have recurring classmates until middle school, where you have different people each subject.

It makes a lot of Japanese media hit differently when you learn how their K-12 program works. In Another, for example, a girl is ostracized by her classmates due to them believing in some type of curse and they pretend she doesn’t exist. So imagine the horror of going through that for years.
