Overall its easy although there are some caveats...

Felt more like an ANTHRO course, history of early hominids, climate change. There's one section of the class that gets a little odd, Gervais lectures about theoretical alien species that can harness the power of their entire suns to preform intergalactic travel and yes he tests you on this.

Gervais means well, but can sometimes come off as pompous.

His tests are DESIGNED to mess you up. For example a multiple choice question might go like this: "Lucy, an early hominid was carbon dated to have been ______ years old" a. 7.1 million b.7.2 million c 7.3million d7.5million so the exams aren't really to test what you know, but rather if you can directly quote Gervais.
