If you haven’t already physically handed me your XP cards, you can simply bring them to the final exam and staple them to it. (If you’re not planning on taking the final, email me and we’ll work something out about your XP cards.)
As for what the final will cover, everything we’ve learned this semester is fair game, including Silver. The exam will be open most things (open notes, handouts, previous quizzes, examples from the course website, Mesa and Networkx APIs, the Silver book itself) but closed Python. Lastly, the exam will itself be at the schedule time as listed in the syllabus: Thu May 2nd, 3:30-6pm. Bring a pencil, as well as your laptop if you’d like to consult any of the aforementioned items.
