Madison Engineering Progression stats

My daughter is in the final stages of her decision process. She is deciding between University of Delaware (direct admit to biomedical engineering, no progression requirements) and UW Madison. We are looking for stats on the percentage of first year biomedical engineering students that successfully meet the progression requirements. She is a very good student and a very hard worker and will utilize every single resource possible to do well, but we are still nervous about choosing Madison when her major is not really a sure thing. Any idea where we can find those stats? I can only find general college retention rates.
