Slides and Module Content
Please note: Your in-class activity is graded. Your first attempt will be graded. You can use your notes and slides if you like. You have 1 week from the date of this module opening to complete the in-class activity. In-class activities are completed individually.
Note: Audio/Video recordings are made in a best effort in case you have to miss class or you would otherwise like to re-watch a portion of lecture. Occassional recording errors (e.g. missing sound, corrupted video, etc.) may occur, and I apologize in advance if a recording is not able to be made available. That said, it is the expectation that you are coming to class in-person. :)
