The course was a useful introduction to the subject matter and provided me with more detail about an area of history I had limited knowledge of. There were a number of minor issues with the course material that could easily be tidied up (including quiz questions which sometimes relied on information that hadn't been provided in the material). There was also very limited activity in the discussion forum.
If you want to complete the course you'll need to do a lot of assignments that rely on peer assessment. There is one every week, plus a longer essay as a final test. I actually found them a useful way of making me review the material provided. Overall, worth doing if you are interested in the subject matter.
