The norms are MUCH higher than those for our state test (11th grade) for example, but I would still be more impressed with a 90th percentile on the SAT then than now,

.
For scoring, the math changed less dramatically than the verbal.
Did they renorm the ACT, GRE, GMAT and the PSAT as well?
That's a big change on the SAT, especially at the higher end. I took the SAT twice before renorming but my scores did not change much. I would have 800s today. Sort of puts things in perspective when I hear about perfect SATs today.
