The courses that the degree audit shows,is that what your supposed to take throughout your university

Yes

Somewhere near the top it should say something like
A. Outstanding 6 Units
B. Outstanding 14 Units
etc

And on the bottom section it will have a list of all the possible courses that fit into section A, B, etc.

Just be aware that there are sometimes discrepancies between the course calendar and degree audit, so you should check both. If you do notice any discrepancies it's almost always the course calendar that is correct, but you should confirm this with your department.
