All information about this course, and all weekly problem sets, can be found on an Overleaf project at https://www.overleaf.com/read/sjxkpgrkyctc. It should be possible to access this project without creating an overleaf account. If you do choose to create an Overleaf account (which just requires entering an email address and creating a password), you should use your Notre Dame address; Notre Dame provides free Overleaf Professional accounts for all students.
