My biggest hang up right now is timing... I would love to take the class, but I am worried about how demanding the time schedule will be. This would be my first class in many years. 95% of the summer is completely free, but there is that few days that are completely packed. I am not so worried about the studying. I am worried about assignments and tests. Can someone tell an "old lady" how these online classes are structured? Is the time line strict or is it more learn at your own pace with a few set deadlines?
