No, I mean something else. That's why I've said that education systems vary so much.
In my country, after four years of "Secondary Education" in high school, you may take two additional years of Baccalaureate, which may or may not be at the same high school, then you take nationwide exams, and the score you get allows you to enter university.
I think I was told that, in some countries (maybe the UK?) you can be in a "college" while taking the equivalent to those Baccalaureate years (so you're not an university student yet).
