Sometimes a student may be passing a class late into the term but then an extenuating circumstance, e.g. family emergency, illness, etc., arises that makes it impossible for the student to finish the class. Rather than dropping the class totally and having to retake the whole class again he/she may want to discuss the possibility of an "I" grade with the instructor. An "I" grade allows the student the opportunity to make up the missed work before a certain period of time established by the instructor. Once the missed work is completed, then the instructor changes the "I" to the grade received in the course.
