Online Courses

Harvard is pushing their EdX program for alumni and spouses so my husband and I signed up to take a course in neuroscience. What I have seen so far in the registration process doesn't indicate anything about how much time the course itself takes let alone the time I have to take to learn all this stuff. I am not complaining since it is my choice to take the course but I wish I knew what to expect. As I have indicated in other posts, I get fidgety when uncertainty is involved.
