Did you read the methodology?
Do you understand how higher education works?
Did your institution teach statistical literacy?
The old way of doing things: recruiting only privileged students of the white upper middle classes and then bragging about rankings that show successful grads is meaningless.
The real struggle is educating people who aren't likely to succeed no matter what the school does. Otherwise the rankings only mean: "We have a good track record at recruiting children from privileged backgrounds."
REAL education is harder than that. To have a chance at impacting the lives of people in a positive way involves a bit of risk. Look at where Harvard falls on that particular ranking: it may be an excellent education, but it's not likely to improve the students' lives because you had to win the cultural lottery to get in in the first place.
