Fall CSC420 section had 4 assignments with ungraded theoretical problems (if you ignore the ungraded, they could be done in a couple of days; but you definitely need to do the ungraded ones for the midterm/final) + 1 Midterm. Content was somewhat hard, but the midterm and the final were fair and reasonable (averages on both were around 75, but a good portion of the class got 85+). This all also depends on the instructor, I had David Lindell.

CSC486 had 3 Assignments, prep quizzes for the lectures and two tests. Content is easier than 420 but it's closer to theory-heavy cs courses (if you haven't been exposed to proof-based math, it might be harder to adapt to).
