I can't believe some of you have 10+ periods

That's insane.
My middle and high schools were only 6 periods.
For those of you who have 7 or more, how long are your classes?
My classes were roughly 45-50 minutes each with a 30 minute lunch that felt like 15 minutes. We also only had 3 minutes between classes.
The highschool at home has seven periods a day (or you could have another, if you came to school extremely early). The classes are about 50 minutes long and they have four minute passing periods. They also have a seven minute 'brunch' break in the morning and about forty minutes for lunch. My middle school was pretty similar too, but periods were only 45 minutes and we had a fifteen minute brunch and five minute passing periods.
My schedule at this school is really confusing. It rotates every day and stuff. Monday schedule: Bio, Bio (Mondays have double lab periods for science), assembly, free period, lunch, math, french, history, english. Tuesday schedule: Bio, free period, meetings (for clubs and stuff or advisory sometimes), history, lunch, math, french, english, free period. Wednesday: Free period (meaning I get to sleep in later

), history, advising, english, lunch, math, french, free, bio. Thursday: history, english, lunch, math, french, bio, free period. Friday: English, free period, assembly, bio, lunch, math, french, piano, history.
And later on in the year my free periods will be filled with public speaking and information technology.
