do I have to take extra classes to prove quant skills?

Hi all,

Here's a brief rundown of my profile: I graduated from UC Berkeley with a 3.8 GPA in Political Science. I took the GMAT and got a 730 (47Q, 44V). I've worked at IBM for three and a half years as a marketing professional, and have been promoted twice. My ECs include being on the board of an education tech nonprofit.

At UC Berkeley, it is mandatory for Pol Sci undergrads to take a course called "Political Science 3 - Introduction to Empirical Analysis and Quantitative Methods." Basically, it is straight up statistics applied to political science, and my professor taught straight out of a standard stats book that our normal "Intro to Stats" also used. I got an A. However, this course shows up on my transcript only as "Pol Sci 3 - Empirical Analysis," so I'm not sure if adcomms will immediately recognize that as essentially stats course.

I also took a lot of courses within Pol Sci that were heavy on micro and macro econ (I passed out of the 101 Econ course in the Econ department through AP credits). That said, I didn't take calculus in college.

Is it necessary for me to take an extra statistics and/or calculus class at a community college or extension program in order for my application to be competitive? My concern is that adcomms may "doubt" my quant skills otherwise. Is this a valid concern, or am I overthinking?

I'm aiming for a corporate marketing career post-MBA at a top 500 firm, and am aiming for M7 and t15 programs.

Thanks!
