That bit of the paper could have been a bit clearer. I simple downloaded 100 questions at random from a website that hosts lists of exam question. Am checking with Samir regarding if he did any further selection beyond that.

If one gets to chose the questions and assemble the questionnaire then shown to all study participants, I would submit that more or less arbitrary study results can be generated by, consciously or subconsciously, picking the "right" questions. Curiously, the two people that "reviewed" the questions here were "a Wikipedia editor and administrator," and a "long-term volunteer editor and administrator of Wikipedia" and "founder of [...] the Wiki Project Med Foundation."
Not being negative or anything, but if you're trying to scientifically evaluate whether a given exam prep book improves students' grades, would you let the editors of the book prepare the test exam?
