Good idea. I see you know who's Archimedes! You know, if I was ~30 years old at least, I would have a dozen pretty crazy ideas what I can do with such beautiful girl. But now... only geometry haha!
Literally translation is right. "Two" is "bad mark" in Russian schools, we use old [very old] German system of marks. "Sit down" - standard teacher's answer, because, traditionally, the pupil stands when answers to teacher. That's an archaism, I guess, for you [I know nothing about secondary school in Sweden]
Yes, 1 to 5. Strict... My friends in USA does all possible their children were in strict quality private schools, not "humanistic" state [public] ones They realize: semi-literate fool has no future My daughter is a quantum physicist, after Moscow University [one of top ten world universities] - she was in STRICT school.
It's a death of the all Western World and culture, when pupil answered to the teacher: "Fuck off, I'm not ready to answer". The school has to be strict.
