Apologies for the submission error on Canvas for problem set 1. As outlined in the course syllabus, please ensure that all problem-set assignments are submitted in PDF format through Canvas at the dates and times listed in Canvas.
I have rectified the Assignments section on Canvas to exclusively accept problem sets in PDF format from now on. The deadline for uploading problem set 1 is tomorrow (Wednesday, January 24) at 2 p.m. You can submit it here.
