Do you know what the usual movement is like off the OOS waitlist?I don't think this is necessarily true. This sounds like it might be calculated from the UTSW class size (230) - # of match offers (220) = 10.
This calculation does not take in to consideration spots that were already set aside for students in programs like BS/MD.
A current student estimated that 50% of the final class comes from pre-match, 10% from special programs, and 40% from the waitlist.
