Less interruption? How so? When we were in high school (long before)
there were no "bathroom passes". Classes were 50 minutes with 10
minutes between. Young adults were expected to be potty trained.

San Jose high school classes are an hour and 45 minutes long, which is
double your class periods. On Mondays, they're very short. About an hour.
