I find that this z block is useless and very inconvenient. Most of the teachers that I have class with use all 90 minutes that each block is. Shortening each block causes several things to happen. So far this block has been confusing because of the time changes. Also, for those teachers who use the entire 90 minutes will want to use the 90 minutes every day in all of their classes. Before the z block happened every class will normally start roughly 5 minutes late because of human nature and other little things that teachers have to take care of. That leaves 85 minutes of learning. When z block was thrown into the schedule it would take maybe 10 minutes to start class because of the confusion and because some of the teachers would try to squeeze in one more thing or two about the subject. This leaves roughly 70 minutes of learning, 15 less minutes for learning. For some classes, for example Calculus, we will start class before 8:00 because there is a lot to learn in a short amount of time. AP Physics is the same thing. We need the entire 90 minutes not 70.
When we had z block, the first day I tried to use it by studying for my SATs. I found that 40 minutes was not enough time to actually get into studying. I gave up trying to do anything on the second day because overall 40 minutes is a waste of time. Most of the students have at-least or should have 1 study hall in the 2 day rotation. Those study halls are actually useful and helpful because we have time to put our mind into what we need to do. Keeping these is all a student needs; not a 40 minute z block.
