Not exactly what you asked about, but I do have a tip:

Consider skimming with 2X speed.

I went through all three "Fundamentals 1" courses, because each instructor took a different track, and each had some really useful individual tips and tricks. The completely redundant basic intro lessons I just skipped, but more often than not, I would speed the lesson up to 2X and skim. If something new and interesting popped up, I could slow down and interact with the information.
