I am teaching under a block schedule where classes meet every other day for 90 minutes. This means I have 5 classes every two weeks * 90 minutes/class * 3 periods/six weeks * 6 six-weeks = 8100 minutes of class time. In the previous schedule I would have had 55 minutes/day * 30 days/six weeks * 6 six-weeks = 9900 minutes. Does anyone teach a full-BC course in 8100 minutes of class time? Our school district has about 15,000 high-school students (9-12) and we do not have a BC course taught in any of our schools. Can it be done, since AP dates, school assemblies, ... all take away from that available time?
