Pre-requisites at UC Berkeley online extension courses

Does anyone know how Berkeley extension assesses the prerequisites? The pre-req for the basic finance class is Accounting. Will they check my undergrad transcript for an accounting class?

I want to take Accounting, Basic Finance, and one other class at the same time (maybe Managerial Accounting or Marketing or Real Estate), but I'm not sure if this is possible since accounting is a pre-req for finance. If they do check for this pre-req, does anyone have any other quant focused class suggestions? I read in one of the posts that accounting is more of a soft quant, unlike finance and math.

Also, I have a degree in Econ with a crappy gpa, so I've taken calc III, and intro econ courses at the undergrad level. My lowest grade in those classes was a C+ in calc III, and I passed out of stats, calc I and II. (My crappy gpa is from higher level econ classes and pre-med classes.) Should I be repeating any of the coursework? I don't think my grades in each of the classes were low enough to warrant re-taking any of those courses.

Thanks in advance!
