An incomplete is a process where you will receive an I for your grade when final grades are given for that semester/quarter. If you have completed 90% of your coursework and have not been absent (a lot) from class, your professor can allow you to get an I and finish all incompleted and remaing assignments. Unfortunately, you will not get your grade for the class until the following semester. This beats getting a F and messing up your G.P.A. Also speak with your academic counselor about this. You will not receive units until next semester also.
