I'm an attorney. I do corporate work, primarily tech transactions. I'm interested in antitrust/IO, but at a more rigorous level like one would study it in a PhD econ program.

It was just Calc I and some stats course. Would I need to go back and formally take calc II, linear algebra, advanced stats as one offs at local university or something to have a shot at decent, even with a high GRE? Is there any kind of math intensive boot camp or something one can take to demonstrate prereq math knowledge without the burden of formally taking semester+ long classes?

I'm looking into a career change. I'm almost 30 yrs old. I have a grad degree from a top program in my current field, but it's not a math-related field. If I'm serious about getting into a decent program, is it absolutely necessary to correct my formal lack of a math background? Or is it possible to get into a decent program without having taken advanced math classes way back when I did my undergrad. Any suggestions or thoughts appreciated. Thanks.
