I studied a social science in college. I was one of the "mathiest" students in my department, but my experience is more in statistics. I took algebra and geometry in high school, then a few stats courses. Now I'm interested in iOS development, and thinking of getting started with the Stanford iTunes U courses (including the more basic CS course that comes before iOS Development). Will I be okay in the math department? Or do I need to take more general math first? And if so, what math courses would you advise?
