Full Answer

Schools with a fall and spring semester often offer classes during the winter and summer, but these are not counted as semesters. Certain schools use a quarter system, with each season considered a quarter. Two semesters are equivalent to three quarters. Other schools use trimesters, with classes in the fall, winter, and spring. These three trimesters are equal to two semesters. A smaller amount of schools use a block calendar system, where one class is taken at a time in four-week blocks.
