One of my college classmates (at a very expensive U.S. liberal arts college) used to quip "The more you pay, the less you stay." We had two 13-14 week semesters per year (1-week break in each, Thanksgiving in the fall and mid-semester break in the Spring), with a 6-week optional January term between and 14 weeks for summer. Sticker price was $45K when I went there and is now $70k.
