About ClassCatalog

Last updated September 8, 2026

What ClassCatalog does

ClassCatalog is an independent planning aid that brings SDSU class, schedule, seat, professor, and catalog information into one searchable view.

It is not an official SDSU enrollment system and is not affiliated with or endorsed by SDSU or Rate My Professors.

Where the information comes from

  • Class listings, meetings, enrollment details, seat availability, and degree-catalog information come from SDSU public sources.
  • Professor ratings and related review signals come from cached Rate My Professors data.

Seat data is refreshed periodically and may lag behind my.SDSU. Community-submitted professor ratings can be incomplete, subjective, or outdated.
