So, has every non-experimental question been tested in previously administered experimentals. Wouldn't they have to test the whole section together? So, for example has the RC I took on the 2nd, (hawaii, mights) been tested as unit before? Shouldn't the testers that took it on the 2nd contribute the most to the scale, since they are presumably a larger and more representative sample because they all took the exact same scored sections.
I know the testers from the last 3 years somehow bear on the scale, but how exactly, and how much?
