At my high school in South Africa, in the late 80s/early 90s, we had a two-week schedule, so you had to remember not only which day it was, but whether it was week one or week two!
In same timeframe in Sweden we had one schedule with eight different classes every day except the few days when we had a lesson that was two "blocks" long. Everything was in 40 min blocks with a clear pattern of breaks between. We got to copy that down each year by hand on graph paper making the lines and everything. This lead to us mostly knowing our schedules by the second week and hardly having to look at it.
Fast forward a few years and my daughter has 2 different lessons per day, it's communicated with an app and she has to look at it at least twice a week after half a year to figure what day what was.
The best thing ever to only have two subjects per day so you can actually concentrate on the subjects and not try and fail at multitasking the whole time...
