What people actually got
Last observed Winter 20264 terms 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.
Per-term figures stay hidden until each term clears five contributors. 4 observations can support one honest number; they cannot support 4.

Counts, not a library. Pyko does not host or distribute course files, and this page is not an offer to supply one — the archive is what lets these pages describe how a course is assessed, which matters most where no syllabus has been verified.

What this opens up
79 courses list STA261H1 as a prerequisiteShowing 24 of the 39 that have a page here. The other 40 have no page yet. Listing a course here means it names STA261H1 among its prerequisites — often as one of several ways to satisfy the same requirement, so this is what STA261H1 makes available, not what it alone guarantees.
