<p>The calculator uses a particular scaling curve. For example, for math, it is using 800-800-770-… which is more generous than average and not typical for recent tests. So, take the numbers with a grain of salt.</p>
<p>^^^Yea, what he/she said about Math. I entered my stats from the May SATs, and it guessed my Reading and Writing scores perfectly, but it gave me an 800 on Math, when I actually got a 790 (one wrong).</p>
