I did take this test last Saturday. I found it a bit challenging. Strangely enough, the most challenging questions seemed clustered together for some reason. That might have resulted from the test's psychological effect on me though--buckling under the pressure of one or two difficult questions, and then finding the next few difficult as a result.
Most of the schools I've looked at seem to want the GRE Lit test. Columbia didn't, but it was definitely atypical.
