I compared the scale they have in the back of the sample test for the 2009 (bought) one and the 2007 free one available on the ADA website. A 29/40 in QR is a 20 according to the 2007 one, but a 17 according to the 2009 one.
Do the scales vary for each test or did they just change the scale? Thanks.
