Washington University allows upperclass students to self-schedule their examinations to suit their individual study needs. With the exception of the typically four or five courses with the largest enrollments (whose examinations are spaced at minimum two days apart) students individually decide when and what exam they will take during an open two-week exam period. Many upperclass courses have no examination, but rather base each student's grade on a paper, a series of papers, or a final exercise such as a simulated trial or negotiation session.
For first year students, Washington University schedules final exams each semester a few days apart to maximize the opportunity for careful study and preparation.
Our students never need worry about having any of their exams on the same day or even on concurrent days.
