    I'm very surprised no one (that I know of) has plotted the score distribution of the Physics GRE form GR0877. The data comes from the table in the practice exam book. Sample size = 14,395 exams between July 1, 2007, and July 30, 2010.

    Cummulative Distribution Function (CDF)

    It's a very nice Gaussian.
