Math 110AH does not have any pre-requisites. Here is the course link.

EDIT: Oh wow, but Math 110A DOES have 115 as a pre-requisite. I never looked at the normal 110 listing. In that case, I'm guessing there's a mistake in the listing for 110AH. I will call the math department tomorrow.

Currently I'm Math/Applied Science. I want to switch into Math/Econ. Shouldn't be difficult to do right? And I may want to do graduate work in Econ or graduate work in Math, I'm not 100% sure as of now.
