I just finished this course. I generally prefer the audio to the video because I can listen while walking, but this one needs to be video so you can see the structures. I have been watching while using the climbing machine at Gold’s Gym. It is perfect, since I have no place else to go and have to give it my full attention. When I tried to watch these courses before, I always tried to “multitask.” I suppose running while watching is multitasking, but when you get in the rhythm the body goes auto-pilot. I recommend the course. Next time at the gym, I will start one on geology.
