Note that while there are no videos on sets, they are reviewed in the lab and used in the programming assignment.
A PDF version of the textbook is also available here
You will be asked to log in with your CNetID before you can see the textbook.
Please note that the pre-recorded lectures cover largely the same material as the book. We recommend starting with the pre-recorded lectures, and then reading through the book (but do not feel bad if you find yourself skipping large portions of the textbook, if you feel they tread on material that you already understood when watching the lectures)
Zoom Sessions¶
You will find the links to the Zoom sessions on Canvas.
