WuthinWithin the context of post K-12 establishments, such as in [[medical school]] or other intensive university program, a '''block schedule''' may mean taking one class at a time, all day, every day, until all of the material is covered. A normal university course might then be completed in three or four weeks of focused effort on a single topic. This is sometimes called "One Course At A Time" ("OCAAT") (see [[Colorado College]] and [[Cornell College]]). When used as a supplement change instead of the normal schedule, this approach is sometimes called a ''mini-mester''.
