National average is converted to a raw 70 with a SD of 8. Most schools reconvert the 70 to an 83 and then go from there. The national average will be a relative thing. I thought it was the easiest test and I ended up 9 (1.125 SD)pts above national average. I thought the biochem was an absolute killer and I am sure I answered fewer correct than the Histo (a lot fewer), but I ended up 13pts above the national average. Again, it's a relative thing..... like the MCAT..... an easy test doesn't equal a good score.
