Not too easy. Not too difficult.
I'm not a big fan of online courses. Harrison was good on grading and cutting slack here and there, but he was inconsistent with due dates. I typically enjoy a well structured course that has the same due dates every week, and Harrison's were always changing. He also makes a good amount of writing and grammar mistakes, which is bothersome but tolerable. He makes it really difficult to pass the tests if you haven't read the entire chapter. I recommend getting an online version of this course's textbook so you can search keywords you may have overlooked from reading or skimming. If you do the work, its easy to get a decent grade.
I honestly enjoyed Western Civ I more than II because I find a lot of the post-Renaissance stuff pretty boring. The main themes of the course were revolution in Europe, namely France, Industrial Revolution, the World Wars, and Cold War. 20th Century history is a little played out for me, but if you find this stuff fascinating this course is for you.

Advice for students:
I found having the online Brytewave version of this text helpful because if I missed something I could just search the entire text for it. I also recommend doing the study guides, it's hard to get a good grade on the tests even if you've completed them.
