Hi Wendy,
Thanks for writing in. I'm a big proponent of candidates who quantitatively weak taking additional coursework. If you think the best option for you is the community college, I'd suggest that you go ahead and enroll. If you haven't finished the course by the time you want to submit your application, you can write a short optional essay where you say you are taking the course, spell out what you're learning, and offer to submit the final result when you have it.
Good luck!
