Alternatively, the university may have "quarters" or "trimesters," which are about 12 weeks in length. In addition, universities very often provide six- to eight-week summer terms. These are optional, and students attend if they wish to get through their degree faster, to decrease their course load during the regular terms, or to make up for courses not completed successfully during the regular academic year. There a two- to four-week break in the winter (December-January) and a one-week "spring break" sometime between early March and mid-April.
