But you said that in your husband's experience people's scores didn't go up with multiple testings, and I am one data point that demonstrates that scores *can* go up the more you take it.
The only leveling off for me came between the PSAT and the last time I took the SAT.
I'm guessing that most of the multiple testing he saw was a cluster in the Jr. and Sr. years, rather than what you were doing which was one each year. Your experience with the leveling off may support that.
(I just did really well on the PSAT.)
Well, that's not a bad one to do well on. My DS got a national merit scholarship out of his that paid for half is college tuition!
