I wasted some time and remember very little at this point.
I'd definitely try to remember things like Eichinococcus = liver cysts, fish tapework = B12 deficiency, Hookworm = Fe deficient anemia, parasites in general = eos, and maybe a few general treatment principles. That's mostly worms, I know there are other types, but you get the idea.
Edit: I haven't taken the exam yet, so take that for what it's worth. Just my guess.
