It was relatively simple to do online, and can be done quickly (I finished in a little under two days) if you put in the time. You have up to one year to complete the course, however.
After registering and paying, it only takes a few minutes for the confirmation email so you can get started at any time!
There were some minor grammatical and spelling errors on the slideshows, (and the mouse pointer of the instructor should have been moved off the slides on the screen) but other than that, the course was good.
