Does NMSC superscore SAT?

<p>Does anyone know if the National Merit Corporation superscores a semifinalist SAT or do they just take the best single sitting score?
D had a higher overall score in June,2008 than in October,2008. Her CR score went up 50 points this time and is her highest,but her math and CW were higher in June.</p>

<p>I heard somewhere on this CC board that as long as the overall score is over 2000, National Merit regards it as acceptable validation of the PSAT score.</p>

<p>You could always call National Merit if you wanted to check this.</p>
