The course itself was great. However, the timer at the bottom of the page is ridiculous. If the whole point of it is to stop people from cheating that doesn't work either because it's an open book test. Everyone reads at different times and when I've read it thrice and still have to wait three minutes it makes me not want to finish at all. The timer at the top of the page also should only run went your doing the course not when your on the page. My laptop ran out of battery and shut down and the next day it said I had spent 19 hours and 56 minutes working on the course.
