"Those sources told the Star Tribune that Diedhiou’s English proficiency test scores were cited as the major concern. Minnesota does not have any thresholds for proficiency test scores set in stone, director of admissions Rachelle Hernandez said, but the results are considered as part of a holistic review done for every applicant. After being advised by other members of the department, Hernandez ultimately makes the decision whether to admit the prospective student."

Some people are attacking Gopher Warrior here, but he's always been consistent in his belief that Gaston was shaky on both academic
and athletic levels. I think it's reasonable to believe the staff could just decide that they don't want Gaston at this point and that might influence the decision making in this case.
