<p>On the packet today, it said that you shouldn't omit, and that guessing doesn't affect your score....</p>
<p>But on the SAT, when you guess, you get penalized</p>
<p>Can someone explain why this is? At the end of each section, I just guessed on multiple questions, and don't really know what that does to my score...</p>
<p>omitting questions lowers your score actually.</p>
<p>There is no guessing penalty on the ACT. In a very hypothetical situation, if you know 30 out of the 40 on a section, you would probably get a 26 or so. However, if you guess on 10 of them, and have a 1 out of 4 chance of getting those right, that would add 2-3 points to your original 26 or so and you'd get a 28-29 or thereabouts.</p>
