Yes. You can't audit without being registered, and,
you must take all exams and do all homework.

The only difference is the grade is Pass/Fail
(and the fact I'm three times the age of the students,
and, often twice the age of the professor!).

Definitions differ. When I was in college (and indeed when I was an
instructor at a different, private, college) "Pass/Fail" and "Audit"
were completely separate modes. "Pass/Fail" was as you describe.
"Audit" didn't require exams, though they were voluntary. Professors
couldn't stop someone (indeed didn't know) if someone was taking the
course "Pass/Fail" but could and certainly did, if they wanted to
audit a course.

I have one advantage over some students, in that
I have an application in mind when the professor
discusses things - and I bring that to the table.

When I show the math, I show everything, down to
the last detail - for which I've received kudos
for in these classes.
