<p>Does that look correct, that out of 54 total questions, 51 were correct, 1 was incorrect, and 2 were omitted, and I was scored with a 720? This would mean that I was deducted 80 points for 1 incorrect and 2 omitted answers.</p>
<p>Yup. To score 800, you need them all correct. Depending on test administration, to score ~770, you can only miss one but leave zero blank. At the top level, leaving one blank is practically the same as missing it. I would guess that three wrong would also be a 720, or perhaps 710. Thus, the ‘penalty’ for guessing…</p>
