I'm starting a PhD program in anthro soon and we have the same two language requirements with an exam at the end of the second year. Thankfully we can swap statistics (or another science/math-heavy specialization for one), but it's been years since I took Spanish. I'm thinking about going with Chinese anyway since it will be much more useful for my dissertation, but that might be problematic since the program highly encourages you to take a language with a large body of existing anthro-type literature and Chinese doesn't fall on that list. I'll have to appeal that, then hope I can manage to a respectable level in the language in two years - yippee! I'm planning on taking at least two language courses over the summer to help with that, and I'd suggest looking into that on your end. If you could somehow swing a summer FLAS fellowship that could help out with money.
