Just get used to preparing for bad tests. Many event supervisors likely read the rules once or twice and then write a test on the topic in general without following the rules word for word. College professors that write tests are probably going to focus on what they know the most about or do research on more than anything else, even if that area isn't focused on in an event's rules. And you're going to find you'll have very little luck trying to get an appeal for a written test. Chances are when you're screwed with a badly written test, everyone else will do just as badly; and if you've prepared, you should still do well. This isn't always the case, but most of the time on difficult tests that don't follow the rules, the most prepared team will still likely win.
Last year, at regionals, we were to ID every single specimen to species, but we still got 2nd since every other team was as clueless as we. And the girl who beat me was absolutely insane at ID events and completely deserved that first (luckily she graduated last year
