Taking University courses as Audit

[CLW]

Hello,

I have a dispute with my University.

This semester they suddenly introduced a new rule that the limit of credits is 22.

That brings me in trouble with the courses I need to attend in order to graduate next semester.

Anyway at the beginning they told me I could register two courses as "Audit" so that they show on my transcript.

Yesterday I talked with staff from our office who told me it is not possible because for Audit classes the credits still will be counted.

So first, what is the purpose of these Audit classes? I just sit in and no need to take exam? Do I get a grade or not?

Maybe some has experience or can explain me? Thank you!
