<p>I think that the adjusted curves need to be taken with a grain of salt (if that’s the proper idiom). Unless CB took the MC data from 2009 (which I doubt they did or they even have) and ran everything through with essay and adjusted MC score and then had a person determine the curve, the adjusted curve is nothing but an estimate. Sure, it’s the best we’ve got for predicting what percentage is what score, but I don’t know if it’s just a CB guess or a curve re-created from re-tabulated data.</p>
