No grade may be changed by an instructor after it has been posted or disclosed to a student unless there has been an arithmetic or administrative error that has been certified in writing by the instructor. The method of evaluation is indicated at the end of each course description in this Bulletin, and a student's grade in the course will be determined in large part on that basis. In most courses, a final examination is held during the examination period. Once a student has been evaluated in a course using the method indicated in the course description, the instructor may raise or lower the student's grade on the basis of class participation. Failure to Take an Examination Written examinations are held at the end of most courses.
Every student is required to take the regular examinations unless excused.
If a student fails to take an examination, a grade of F will be recorded unless the student has been excused from the examination or has obtained the dean of students' permission to drop the course. No excuse for absence will be granted except by the dean of students and then only for illness or other emergency. Application for excuse must be made in writing as soon as possible but not later than one month after the date of the examination. Second, the student may take the next regularly scheduled examination in the same course, taught by the same or a different instructor, for a letter grade. The examination, however, may not be taken after a student has been excluded for low scholarship, and permission to take an examination before the regularly scheduled date and time will not be granted.
