Should I guess on the ACT? The answer is very simple: YES! because its fun!
On the ACT, you are scored based on the number of answers you get correct.
There is no penalty for incorrect answers. Therefore, absolutely answer all the questions, even if it’s a blind guess! Watch your time and leave that last minute for bubbling in any you haven’t gotten to or any that you might have skipped.
Just make sure that your guess is an educated guess. If you can eliminate just one of the possible answers, that considerably increases your odds of guessing correctly.
