The PSAT is similar to the SAT, just fewer questions. My older two took the 2400 format SAT & PSAT, and you could get a good idea of how they would do on the SAT by looking at their PSAT scores. (Now the College Board has the wacky 1520 limit on the PSAT vs 1600 on the SAT, so it is a little more difficult to compare.)

While the PSAT/SAT may be easy for some, the College Board has always tried to make the tests such that the average score on each section will be around 500. I think that the current SAT format average score is about 1060.

The good news is, if your daughter can hit a perfect or near perfect score, that she will be NMSF when she takes the PSAT junior year. As a US citizen living abroad, she still qualifies for NMSQT. The citizen living abroad cutoff PSAT score is always very high, so scoring well as a freshman bodes well for junior year.
