ClassMaxx is not affiliated with University of Colorado Boulder. Seat counts come from the school's public class search; grade history from published distributions; earnings from the U.S. Department of Education. We never ask for a school password.

The iPhone app pushes the alert the second a seat opens, builds four ready schedules from your degree audit, and ranks sections by real grades. Free; a $4.99 Fast pass per semester makes alerts instant.
