I had three lessons for each subject per week, with two being an hour and a half and one being two hours, so I had five hours for each subject per week. I also had a hour long tutorial at the end of a Tuesday, although normally we were allowed to leave after half an hour.
As for free periods, I had three, although one was at the beginning of the day and one was at the end of the day, so I only had one long break every week.
