The issue is that medical schools need to fill up their classes, but until they know how many students have CTE, they cannot make WL decisions. It would be a risk to Georgetown to accept WL students only to have all of their current WL A's CTE, a situation where they overfill their class.
Ideally, students with multiple A's should CTE and formally drop their WL A's so schools can make further WL decisions. But I'm sure there are students who are waiting for financial decisions, in between two schools, or even just sick of the process (and taking a break before making a decision).
I just wish the CTE deadline were sooner. I'm submitting my reapplication while still waiting for WL decisions.
