I am wondering how the curve works for SAT subject tests.
With the regular SAT that is fairly easy because a the test takers are generally representative of most school students. However (at least in my state) the SAT subject tests are taken by the rare braniac who wants to go to difficult to get into schools. I would think this would skew results heavily towords higher scores causing a less leniant curve, however the opposite. SAT subject tests seem to have a more leniant curve then the general SAT.
Where do they get the data in order to fit SAT subject tests onto a curve?
