Quiz 1 is now on the Moodle. It will become active at 4 PM MDT on Saturday, September 15th (i.e. in roughly 15 minutes from the time this post appears) and will stay active until 11:59 PM MDT on Friday, September 21st.
You are allowed one attempt at the quiz, so make sure you are in a situation where you will not be interrupted and that you have access to all of the course material (i.e. lecture slides, your notes, and the textbook).
I will remind you to take the quiz several times this week. It's up to you to take the quiz before it closes on Friday night. If you miss the quiz, you miss it. It will not be reopened after it closes.
