If you are going to apply for January 2012 admission and your application deadline is before mid-November 2011, take the test before July 31.
Scores for the new test, beginning August 1st, won't be released until early November because the ETS needs a large data set to establish the new scale and the percentile rankings.
They will replace the 200-800 scale with a 130-170 scale. On the old scale, a single increment was ten points, so a 630 and a 640 were really right next to each other, not ten points apart. After August 1st, one scale increment will be one point.
