Point of clarification: We (Columbia Orthopaedics) are completely separate and have no affiliation with St. Luke's Orthopaedics program - since they are a "sponsored" hospital of Columbia University, however, they are also part of the Beta-test site. So if you have applied specifically to St. Luke's you would need to speak to their academic coordinator to determine schedule flexibility.
I hope this clarifies your question -
