If you have any Incomplete (I) grades, you will not be able to graduate and receive your diploma. Even if your Incomplete grade is not a part of the degree you could potentially graduate for, you will not be able to graduate. An example of this would be having an Incomplete grade in a Geography class and having completed and passed all the required courses to earn an associates degree in computer science: the Incomplete Geography class grade will not allow you to earn the associates degree.
Addressing Incomplete Grades
Meet with your advisor first. They may recommend reaching out to specific academic departments and will assist you with this process.
