Well, that's true of every science. I guess I just find the non-math sciences pretty easy due to interest, even a few classes in. I've never taken anything super advanced in those fields, though.
Edit: Mind you, I find the base of Astronomy math to be much easier than that of physics, because it's just so much more solid with such easily observable examples, compared to a lot of the physics problems that they have you do even from the very start that just seem like crazy bull**** a lot of the time.
