As of fall semester 2011, Amherst College adopted the current three digit course numbering system. Prior to that time, course numbers were two digits.
The new numbering system now assists students in determining the level of preparedness expected for each course. The system is described as follows:
100-Level Courses Introductory or introductory sequence courses.
200-Level Courses Courses above the introductory level.
300-Level Courses Courses which require some preparation or pre-requisite, upper level seminars.
400-Level Courses Courses at a level requiring departmental expertise or experience, upper level departmental major requirements and seminars.
290, 390, 490 Special Topics Courses within the numbering system described above
498/499 Thesis courses.
