I don't think I'm gonna understand your schoolsystem. Tho I think it's good that your teachers reached this with their sudden exams, that students come early and study well
it does be very different. the relationship between our professors and us is a little bit hard to explain. here teachers always feel there are many duties for them to take care of their students which has nothing to do with students' ages. when kids, we get their cares for eating and sleeping and playing, when universities, they still care for our study especially attitude, they will make some steps to notice/warn us when they find us a little bit slackened
this year i am in advanced class, our teachers are more carefully than public situation before. they even look everyone of us as their own child
and our mates are really talented but at the same time they dont want to make our professors disappointed. we look them as not only our teachers simply but also our friends or parnters
if some teacher said something, maybe just some words alone about that he found us not to reach his goals at one class, we would discuss this right now after class and ask ourselves to give him more confidence in next.
