One academic year at MIT consists of three trimesters. Each trimester being equal to 12 weeks - the same as a traditional semester. If you use the 3 trimesters you will use more of the summer break.

So in essence by using either the 2 semesters a year of the 3 trimesters a year, you will have the same student learning experience but will complete in a shorter time.
