<p>Have you guys ever heard of someone getting a higher score as a result of a hand verification? How likely is it for the answer sheet scanning machine to make a mistake?</p>
<p>Not likely. Besides, no one is going to catch the mistake, especially not if it improved their score.</p>
<p>I’ve read that some people receive noticeably lower scores, get their tests hand scored, and come out with higher scores. I’m asking if this kind of thing happens on occasion (like 1/1000) and not just 1/1,000,000.</p>
