Spring 2025 (01/25/2025 - 05/22/2025)
The semester has 15 class meetings including the final exam. Clicking on a class day below, you should find the class module for the day including lecture notes, assignments, and others. The instructor releases the content for a class generally on the Monday before the class. However, the instructor often makes update to the module content after the initial release. You should check this page often for up-to-date content.
In case you encounter a problem when viewing class content, such as, a broken link, please report it to the instructor immediately.
