Actually the 4 a day, new 4 next day, then back to original 4 classes is not Madeira. It’s a local day school’s block schedule.
Madeira has what I call a module system. Madeira it’s 5 little “semesters” of 5 weeks each. Every 5 weeks the classes can change. Madeira may have blocks within its weekly schedule, but I believe it was 3 or 4 classes each 5 weeks. I don’t know if each day is the same. Obviously we asked a lot more questions about the 5 week modules.
Every school we’re looking at has some sort of block schedule—classes are not the same every day.
