That's better than Boise State University's four-year graduation rate for all students.
(I'm certain BSU's not alone; as a result of its success in football, critics harped on the 6% four-year graduation rate, which I understand has now reached 8%).
A four year graduation rate shows how uncommitted the current university scam is to its students. They make impossible to schedule all the courses you need in four years to extract more money in fees, etc.
