“Stanford is the school of choice for the scholar-athlete. In the four classes entering the University from 1994 to 1997, the average freshman male athlete had logged a 3.73 high school GPA and a 1,215 SAT score, according to NCAA statistics. Female freshman athletes during the same period had a 3.87 GPA and a 1,151 SAT score. By comparison, the averages for all Division 1 schools combined were 2.97 and 997 for males and 3.29 and 1,007 for females. At Duke University, another school known for academics as well as athletics, incoming freshman male athletes had a 3.46 GPA and an SAT of 1,103, while females had a 3.51 grade-point and a 1,090 test score.”

Those standardized test scores are extremely low, even for the standards back then.
