Winter 2018 Calendar
This page contains information on the rough timing of topics, assignment due dates, exam dates, and other important milestones. The selection and ordering of topics is correct except possibly at the very end, where somewhat more or less might be covered depending on timing. Due dates are also precise. The exact timing of lecture topics will almost certainly vary from this, and readings (all from the textbook, "How To Design Programs") are linked to the timing of lectures. DrRacket implements a series of language subsets, and the changes from one level to the next are noted under the heading "Language Level".
