Google the phrase "McCain graduated 894th out of a class of 899". Interesting comments come forth.
That wik site is not factually reliable.
John graduated 5th from the bottom of the class. I just asked my husband how many in their class graduated. He said 800 and somehing. I am not about to count the photos in his Lucky Bag --- the name of the yearbook.
John was not a serious student. His grandfather and father were Academy men and John was 'expected' to attended. He rebelled... but never enough to flunk out or get expelled. Party time.
