Cornell students study one course at a time (commonly referred to as "the block plan" or "OCAAT"). Since 1978, school years have been divided into "blocks" of three-and-a-half weeks each (usually followed by a four-day "block break" to round out to four weeks), during which students are enrolled in a single class; what would normally be covered in a full semester's worth of class at a typical university is covered in just seventeen-and-one-half Cornell class days. While schedules vary from class to class, most courses consist of around 30 hours of lecture, along with additional time spent in the laboratory, studying audio-visual media, or other activities. Colorado College in Colorado Springs, Colorado; Maharishi University of Management in Fairfield, Iowa; Quest University in Squamish, British Columbia; Tusculum College in Tusculum, Tennessee; and The University of Montana - Western are the only other colleges operating under a similar academic calendar. Cornell formerly operated on a calendar of 9 blocks per year, but switched to 8 blocks per year beginning in the fall of 2012.
