The particular course I’m doing has audio / video as well as reading lessons. I simply pop in headphones so I don’t bother anyone else. Since I can easily save my position, I can take a break, turn off my iPad drink some coffee and pick up right where I left off.
After a week, I’ve finished a 5 hour course! It would have taken me months to find 5 free hours of time otherwise to finish this course.
I can’t wait until I find my next course to work on, when I’m on the way to work on the bus.
