Yeah it is c: Although in my case, we did have a teacher present. Just not very often haha. Besides, it's also hard, because the supervising teacher may not want to make any big decisions e.g in my class, half the time, most of the class didn't get the notification for a test, and we were informed maybe 3-5 days before the test that there was a test, meaning that half of us wanted extentions etc but the supervising teacher couldn't make the decision - she had to contact the main teacher who wasn't really contactable etc. so meh.
It's nice that you have an exchange student in your school
Wow, your school let's them teach though? Students from my old, old school used to just pester them to make origamis for us haha xD But then again we were like 8? back then lol
