Woah, are you schools all uber strict?Very few teachers stress out about homework's being handed in late, Coursework is a different matter however and you are in deep trouble if you forget that, but normal homework, if you hand it in the next lesson, that is usually acceptable but will end up affecting your end of term grade.
I know how you feel, ARGH it is so annoying. Once I was there and about 20 kids from the same school, in there uniform were at the cinema, I was there with just a couple of friends, and everyone few minutes someone from their group would shout something absolutely stupid, and they'd all burst into fits of laughter. Absolutely ruined the film. ( It was the latest Harry-Potter as well )
