Our High school is A/B block scheduling so the kids have different scheduled classes on A days vs B days. The middle school had the same set up for DD1 but switched for DD2. DD2 had math and English every day for 45 minutes each and then the other classes were 90 minutes on the A/B rotation. I've never asked the teachers what they prefer and my kids have never known anything different so don't find it difficult or confusing to keep up with what day it is, but I grew up having every class ever day so it seems really confusing to me.
