    Only classes with two or more sections are ranked. The waitlist number adds up each section’s waitlist at its longest, so a student waiting on two sections counts twice.

    How we measured this

    We checked every section in Mt. SAC’s Fall 2026 class schedule repeatedly from Tuesday, June 30, 2026 to Friday, October 9, 2026. A section counts as full if any check found its enrollment at the seat limit or anyone on its waitlist. Cancelled sections and sections without a seat limit are left out. Classes that filled before our first check still count, because they were still full when we looked.
