When I was in high school, homeroom was an extra 15 min in 2nd period. Any announcements were made over the PA and we watched TV- channel 1 and our school's channel which was really kinda cool (they did the weather, special announcements, interviews, and funny short videos that they produced). It was second period of the day, but it may have been your first or second class depending on how your schedule was arranged. Juniors and Seniors went 1-6 with an optional 7th period elective. Freshman and Sophmores went 2-7 or some could opt to have a seventh period, but they had to be good students and have a valid reason for wishing to have an extra period.
