•The switch to the 13-15 system was made because it was too hard to differentiate among the people at the top of the pool. However, I seriously doubt you need 100% to get 13 in verbal. Low-Mid 50's should be around 11 scaled, so unless 12 represents a huge range, you don't need to get every question right for a 13. Plus, if so many people were already getting all the questions correct, reducing the number to 60 (starting next year) wouldn't help in separating the 15s from the 13s.•••••Because so many people were getting perfect scores, they could not maintain the bell curve they use to determine scores (ie. they could only allow X% 15's and 2X were getting perfect scores). Their solution was to make 65/65 a range, where 2X just about equals the percentile who get 13-15.
