Well I heard back from Mendoza and from the Math Chair that answered my questions I originally posed regarding the AP credit issue.
- I was correct that he can use the credits he's given from AP Calculus AB and AP Stats to satisfy the Calculus and Stats requirements for Mendoza.
- I was incorrect in my understanding on AP Microeconomics. He actually CAN use the credits he's given from AP Microeconomics to satisfy the Microeconomics portion of his Finance major.
- The AP credit for AP Calc AB CAN be counted towards the Finance major AND the Math supplemental major requirements.
Here is probably the best explanation that I could find regarding how AP credits “generally work”. I found this in the Bulletin of Information on page 41 of the link below. I’ve copied and pasted the relevant section below. The example of AP Chemistry in the text below was especially helpful.

The general guideline is that credit by examination is counted as required or elective credit if the course is required or permitted in a particular college program. Credit by examination is not counted as required or elective credit if the number of the course for which credit is awarded is lower than the initial course required in a particular college program. For example, if a student earns a 4 on the Advanced Placement Chemistry test, the three credits awarded for CHEM 10101 would count toward graduation in the College of Arts and Letters, Mendoza College of Business, or School of Architecture program. The credits would not count toward graduation in a College of Engineering program since the initial chemistry course in this college is CHEM 10171. On the other hand, if the number of the course for which credit is awarded is higher than the initial course required in a particular college program, the credit awarded satisfies the requirement. For example, credit awarded for MATH 10550–10560 also satisfies the mathematics requirement for programs requiring MATH 10350–10360.
