I wonder if you have the right balance of time allocated between schematic entry vs pcb drawing. If your main goal is to show the pcb design part, then I think you may want to consider shrinking your entire day 2 activity to half the day. The reason behind this suggestion is my impression that Day 3 has too much material to cover and will need more time. Alternatively, perhaps pcb design can expand into day 4, and you can shrink the introduction to ULPs. I find that ULPs are very handy, but don't need much time to learn to use the existing ones. It is probably beyond the scope of this to teach how to create ULPs, and so learning how to use one or two basic ones doesn't take much time. Generating gerbers will need a couple of hours, so I would keep that in as you have it.
