Last year, I was given the second edition of the U.S. News Guide to Medical Schools, which contains stats on the entering class of 2005 for every medical school in U.S. territory. A friend of mine recently acquired the third edition, which contains stats for the entering class of 2007. For nearly every school that I am applying to this cycle, the GPA and MCAT of entering classes rose a bit from 2005 to 2007. A few schools' stats dropped, but they were quite a minority. Is the rise in stats part of a typical trend, or is this due to natural year-to-year fluctuation for each school?
