The president's transcript was
published in 1999 by The New Yorker magazine. It showed that Mr. Bush, who graduated in 1968, had a cumulative grade average of 77 in his first three years at Yale and a similar average under a nonnumeric rating system in his senior year.
Mr. Bush received one D in four years, a 69 in astronomy, and his grades improved after his freshman year, the transcript showed.
