The result on the test is normalised to a scale between 0.0 and 2.0, with 0.05 . About 0.1% of the test-takers are awarded 2.0, which is the highest grade. Usually, 145 to 150 marks (out of 160) are required for 2.0. The average normated score for the test is normally around 0.87, and the standard deviation is about 0.40, resulting in approximately two thirds of the test takers receiving a result in the interval 0.50–1.30, and 95% receiving a result between 0.20 and 1.70.
