Her favorite math class in college focused on the theoretical underpinnings of why calculus works. In her final semester at college, Darcy taught pre-algebra and was a teaching assistant in her favorite college class, Real Analysis. Since she was very young, Darcy has always enjoyed math and would like others to have a similar experience. In her free time, Darcy enjoys knitting, downhill skiing, tossing a frisbee, and spending time with family and friends.
