<p>I remember on my first SAT when I got my QAS to find out what were the 2 questions I got wrong that kept me from an 800 on the SAT in Math, it showed me that the answer I put for one of the grid-in was 513 when the correct answer was 5/3. I personally don’t feel I am one to make such a bubbling error but that’s what the machine recorded. Point is that I think the machine can at times have a scanning error.</p>
