My majors were biology and chemistry. No way I could avoid it. And I loved chemistry, but math has always been my weak subject--even compared to English. I did pretty well in geometry, but struggled with algebra and precalc. And in college, I got a D in the semester of calculus that covered derivatives but got a very high B in the semester that covered integrals (over the summer!). I did pretty well in statistics, but I'm pretty sure that's because it was a joke--open book/open note tests, for example.

What I think worked with these courses was "I need to do well..." and as I started doing my homework and checking my answers (or getting my engineering student BF do check them for me) I realized that I was actually getting them right. Helped my confidence enormously.

That doesn't mean I went into chemistry (I don't have the math skills for physical chemistry, nor the spatial reasoning for organic), or that I'm not still a little apprehensive about the biostatistics course I have coming up...
