Would you take a subbing job in a subject that you're not familiar with? I got an offer, actually a request -- they're really desperate. But the subject is really out of my element. It's a low elementary level, so hopefully my lack of knowledge in that area won't be too bad... I've just never really done that before. I'm so used to teaching things that I know and am passionate about. But they want me and I could really use the extra employment (they're desperate enough to take me only on my off-days (every other) and find someone else to cover the class when I'm working) WWYD?
