I recommend that people take the hard advice in the previous post seriously. But for what it’s worth, I will add one remark related to the “format” that seems to have perturbed at least some people. As far as I can judge, the “shape” of the 3704 exam does seem to be closer to that of previous years than the 2201 exam was. I am deliberately describing the correlation in vague terms, as you might guess. (On the other hand, my sister, who works on exactly such issues in computational linguistics, may be able to make it precise. Her concern, to a certain extent, is with the topology of documents.)
