The trick is to get them when they're on academic probation. My school had the "4 horsemen of the math department" and overall their GPA averages tended to be in the "square root club" (sqrt of the GPA is higher than the actual GPA). However, when they were on academic probation it was all A's and B's.

Through a combination of dropped classes, complaints, and bad course surveys, the school eventually picked up that these guys were horrible.

haha, only at tech.
