The Wake Forest School of Medicine PA program has a rolling admission format, although you should note that early applicants are more likely to be prioritised. Interview day will include the opportunity to speak with faculty, staff and current PA students, to interview with faculty, and to participate in a mock IBL session. You would do well to learn more about IBL in advance, to be prepared for the interviews as well as the IBL session itself. IBL, Inquiry Based Learning, should be seen as separate to PBL, Problem Based Learning, and you may wish to do some academic research on its benefits compared to its better known cousin.
