They rescaled the test in 1990 so that the std deviation would be 200 points. So if that's the case that's really odd.

- thaumasiotes 12y ago2014 statistics ( http://research.collegeboard.org/content/sat-data-tables http://research.collegeboard.org/content/sat-data-tables ) say: SD for verbal is 115, math is 120. This must have been what I was thinking of. SD for overall (V+M) score is 218. The overall SD is much more relevant here, but let's note that a difference of one standard deviation is still a very large difference.
