Having attended a high school with a poor math program, I had a similar struggle with math in university. My understanding would catch up maybe too late for a grade, but I kept progressing. Seven years into my career I got a job working for an extremely gifted scientist/manager who gave me several projects that required me to learn math a couple levels above my education. Because the problems were interesting and the results really mattered, I had sufficient motivation to overcome the frustration of learning things that didn't come naturally. I found a way into a company that needed good programmers that grew more mathematical over time, and I was lucky enough to have a highly motivating and supported learning environment.
