With a little nuance, however, you can have an even higher percentage correct and more consistency. In contrast, E/F answers were correct 21% of the time, but with less volatility (E/F was never correct 0% of the time). But the downside to A/F guessing is its volatility: sometimes A/F was correct 50% of the time, sometimes 0% of the time. The A/F answers were correct 24% of the time. If you just want to guess one answer choice, then either guess the first answer choice - “A” and “F” - or the last choice - “E” and “K”. Our analysis showed that a nuanced approach is best. ![]() Half.Īfter C/H, the “worst” answer is the second answer choice, “B” and “G”, which was only correct 15% of the time. So, if students guess the middle answer on these 10 questions, they would, on average, only correctly guess about half as many correct as would be expected. In fact, while we would expect any answer choice letter to be correct 20% of the time on the Math section (because there are five answer choices on this section, so students have a 1 in 5, or 20%, chance of guessing an answer correct), C/H was only correct 12% of the time on the last 10 questions. ![]() ![]() Since the April 2015 test (when the ACT slightly updated its Science and Reading sections), the middle answer choices on the ACT Math section - “C” and “H” - have actually been the worst answer choices to guess, probably because the ACT knows that most students guess C/H, so they don’t want scores to be inflated from random guessing.
