School classes Hi, everybody, So here's a quick scenario: You're in a class in school and you see another class which consists of younger students. What do you call that class? And if the situation is the opposite, then what word should I use? I guess people usually use words like "junior" and "senior", but senior, for example, is used when the students are in their final academic year and junior is for the third, right? What I want is to indicate that the class is just "younger" or "older" than the one I am in. Is there a word for that?
