Pssssst. It sucks.
The content is just. . . there's an 10-minute-long video that has about 3 and a half minutes of content that helps answer some of the questions, while the majority of the questions need looking up on Google. Not to mention they put stuff like, "Mucous membranes are part of the body's first line of defense?" and then put "true" or "false" as answers?? Ew. At least I'm getting a head start, with AP courses and whatnot.
Well, this has been a rant on online courses.
