Matt: “The ACT and the SAT re graded differently. On the SAT, you lose a quarter of a point for every question you get wrong. On the ACT, there’s no penalty for incorrect guesses. That means that on the ACT, if you don’t know an answer, you should always guess. The worse that can happen is that you aren’t penalized. On the SAT, though, guessing a lot can get you into trouble. If you have no idea on the answer, you’ve got a 75 percent chance of losing a quarter of a point, and those can add up fast. If you can’t eliminate one or two of the answers, it’s probably not going to benefit you to guess.”
