This is a student-contributed aggregate, not an official University of Toronto record. It is also not a measure of how hard the course is — a course average moves with who enrols in it, not only with the material.

Per-term figures stay hidden until each term clears five contributors. 6 observations can support one honest number; they cannot support 6.
