I went to my degree audit and i picked a course it said NOT Used which means its not a requirement i understand that. but the question is will it be part of my GPA?

If it has units associated , yes. nut not courses like htl 1bs0 or something like that

It will still be included in your GPA, it's just that the course wasn't used as a degree requirement or elective. For your degree you have to take a certain number of required courses and electives. Once you exceed that number, the rest of the credits don't "count" for your degree, but still matter for your GPA.

It will add to your mark in GPA however it will not count to your degree as a requirement. In the end it does affect your average.
