<p>Say you missed two on the math and it brought you down to a 73.5- would this be rounded up or down? Normally I would think up, but I thought someone said that .25 would round down and .5 would round up to one whole point. It just confused me because that would mean missing two would count off as much as missing five :/</p>
<p>.5 is rounded up.</p>
<p>I’m not entirely sure how the points are tallied up for the PSAT (I know there’s a curve and all that; if someone could explain the scoring system to me, that would be great!) but last year I missed one on the PSAT math and was brought down to a 75. I think that the number you miss is only one part of how your score is calculated. Maybe it depends on the difficulty of questions? </p>
<p>Now I’m curious 
If someone knows how the scoring works and could explain it, I’d be very thankful!</p>
<p>All questions are weighed equally. Each incorrect answer results in a deduction of 1.25 in terms of opportunity cost. Questions left blank are worth a loss of 1. The raw score is then rounded to the nearest integral value, with .5 rounding up.</p>
<p>then the raw score is converted into a standardized score of 20-80 with 80 being the best. generally, the psat scores are curved less due to the fewer questions, easier questions, and the no essay part for writing.</p>
<p>@silverturtle- what did you mean by “a deduction of 1.25 in terms of opportunity cost”?</p>
<p>I always thought it was like this- </p>
<p>leaving one math question blank = 75</p>
<p>leaving none blank but missing one = 75 - (1 x .25) = 74.75 = 75</p>
<p>I meant that if we default to a perfect raw score, missing a question is like losing 1.25 points.</p>
