I take that to mean that you need to have a bachelors in something. Econ is a relatively quantitative field, so that with work experience is likely acceptable.

That really depends on the school. There are many schools where you can get an BA in econ without even taking calculus.

I haven't met anyone in the program with an econ degree. Mostly CS, and engineering. And a few with physics or math degrees.
