Unlike the SAT, you’ll lose points if you answer incorrectly, so only make EDUCATED guesses, don’t just bubble in questions randomly. Other than the resources in my original comment, the main advice I have is to not try to hard to study the night before, as that’s more likely to make you anxious and stressed on test day.
Has your daughter taken AP Bio? If not, I would recommend waiting until she has before taking the test—while the course doesn’t cover everything, it DOES provide a helpful foundation.
Good luck!
