What people actually got
Last observed Winter 20231 term observed
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.
The newest observation is from Winter 2023. Instructors, weighting and exam format may all have changed since — treat this as history, not a forecast.
This rests on 1 reported term. It is shown because hiding it would not make it less true, but one or two results are a datapoint, not a distribution — a single unusual cohort moves this number a long way.
Where the marks come from

Extracted from a published 2025 syllabus by deterministic parser. Components that could not be labelled are shown unresolved rather than folded into a neighbouring category.

What this opens up
8 courses list CHM243H5 as a prerequisiteThe other 3 have no page yet. Listing a course here means it names CHM243H5 among its prerequisites — often as one of several ways to satisfy the same requirement, so this is what CHM243H5 makes available, not what it alone guarantees.
