I'm not sure if this is too broad a question, but I was wondering if it was more common for High Schools in the US (specifically on the East Coast- schools seem to be different depending on where they are in the US) to have seven classes a day rather than six (which is usually they case here in Aus)? As far as I can see looking at websites on the net, it seems that way.
Also, how long was each class period generally? (At my school in Aus, they were 55 minutes long, in the US it seems more like 40 or 45 minutes.) And if it was seven periods how was it broken down: example- did you have three class periods, then recess, two class periods, lunch, two class periods and then home?
