There is no quiz associated with this preparation. But there ARE things to do, as listed below.
All of the following are required except items labeled Optional are, well, optional (i.e., things that may be interesting but do not directly pertain to your success in this course).
During the regular term I "live-code" a solution to problem0.py. That is, I work through that module in front of the class using the projector, with students typing just ahead or behind of me and listening to my explanations of what I am doing and why.
This summer, emulate that activity by using this video that shows me live-coding the problem0 module [22 minutes, 32 MB]. As you watch the video, pause it at key points to think through a problem (or a part of the problem), type in your solution (at whatever speed you like to type), and then see my solution and explanation.
