There are a couple of different things you can do:
1. Leave it for the end (and if you're completely lost, hope that you somehow magically remember). It's better to move on and fill out questions you actually know than end up being forced to leave the whole test blank since you wasted all your time on that one question. If your event is stations though, this doesn't really help.
2. Make an educated guess (or as I like to say, fake it 'til you make it. Also called BS'ing). If you don't know the answer, use context clues from the questions or from your cheat sheet and come up with something that sounds halfway decent. For example, I recently took a Fossils test where my partner and I were struggling to identify the leaf specimen. We ended up going with Platanus. However, the last question mentioned Canadians and people going to IHOP, which made us change our answer to Acer (maples).
3. Do a Hail Mary. Put something completely and utterly random. Two of my friends would write multiple choice options on an eraser and throw it. Whichever side landed up was the answer they put. There was a kid who, on a Fast Facts practice test, put "strawberry cough syrup" for a vaccine starting with "s". It's better to put something random than to leave the question completely blank, and you'll probably never meet that grader so there's no fear of being judged. Who knows, you might give your grader something to laugh about.
