<p>I have never heard of PSAT scores being lost nor have I ever heard of anything but PSAT scores in your junior year being considered for NM. In a unique situation like yours, I'd talk with the GC, NM & CB. Those are always the best source of info anyway.
With regard to letting schools know about your status as a high scoring PSAT test-taker, there is nothing to stop the student from notifying the schools the student is interested in in any case. NM's form given out in the spring of junior year only has space for two schools & for the NMF, you can only officially chose ONE school. I don't know how NMF & NAF overlap; perhaps the GC & CB & NM can help on those.</p>
