It felt like I was taking an exam on the American Revolution, having studied an American textbook, only to find the exam written by a Brit. If I understood the subject in a complete way, I wouldn't have any trouble. Unfortunately, I don't, so everything seemed like I should understand it, but it didn't look like it did in the study materials, so I had to extrapolate/interpolate like mad. Educated guessing as an exam taking method is not as fun as actually knowing the answer.
I'll find out results in 2-4 weeks. In the meantime, I can get back to the rest of my life: prepping for travels, wrapping presents, cleaning the house, making food for the cats, etc.
Thanks for all your support, guys!
