An Incomplete (I) is a temporary grade notation indicating that you have not completed the work for a course before the quarter ended. It is only given because of extenuating circumstances that prevented you from completing your coursework.
In order to receive an “I,” you must request that your instructor assign the grade to you, with an agreement that you will complete the unfinished coursework within one year. Once the work is completed, the instructor can replace the “I” with a final letter grade by following t he instructions for changing grades.
