This is a Red-herring.
She enrolled in the University of Hawaii in 1982 but only stayed for 3 weeks so my guess is she never attended.
Then she attended Hawaii Pacific University instead staying till 1983 and looks like the weather didn't agree with her....so the following spring she transferred to North Idaho College. She stayed there for 2 semesters till she transferred to the University of Idaho the fall of 1984. This seems to be the first major university she attended where she eventually earned a B.A. in journalism in 1987.
What I count is 5 schools attended in 6 years and she earned a 4 year degree over a period of 6 years. Not bad.
And yet, even though she majored in Journalism, there is no record of a single article written by her in any of the school papers. She never appreared on the university radio or any university television show. There is no record of her ever interviewing anyone, and believe me, I've looked. Worse, she once joked she got a "D" in economics, but that can't be verified since her grades are sealed.
We know John McCain graduated 4th or 5th from the bottom out of a graduating class of 899 because those grades are always made public.
Taking Journalism and never writing a single article is like studying art and never painting, or studying acting and never being in a play. So naturally, when it come to her book, there is skeptism.
