The class is completely asynchronous with the exception of the lab which could be either in person or online. There is a textbook for the class which you can find on libGen. You must have it as there are weekly (open-book) reading quizzes. The grade weighting is as follows:
Syllabus Quiz 5%
Weekly Assignments 60%
Thematic Discussion Forum 15%
Weekly Reading Quizzes 20%
The syllabus quiz is really easy, should just be an easy 100% (you can take it many times). The weekly assignments usually consist of making a map in QGIS. It's easy to get a 90% or higher on them, although they can be annoying. Sometimes my TA would grade a bit harshly for no good reason, but as long as you watch the technical demos, you are going to be fine. The forum discussions are really easy, just do them and you'll get a 100% every week. The reading quizzes are free too, open-book and can take them as many times as you would like for a 20/20. Overall, the class is an easy A, would recommend it to anyone who wants an easy science GE. Just know that the assignments can be a bit annoying at times.
