Ah, okay. That is a major logistics misstep, IMO. The KH application is not trivial...essays, short answer questions, and a video prompt, not to mention LOR requirements that are incredibly specific (writing the kind of letter they want is a lot more work for letter writers than the usual LOR kind of deal). So, to have that ready to go and submitted before the MD app is a lot, especially since KH has a September deadline. I plan to call them to inquire tomorrow. Somehow, I feel like there's no way there isn't a workaround for this...but then again, apparently previous applicants could not get around that problem, lol.
On a related note: no MSTP applicants have received a secondary yet, right? I'm almost done with the rest of my secondaries and want to pre-write Stanford's unless it comes before I'm done with my others.
