Look at the previous threads for HBCUs. There’s a consistent theme that is associated with them being slower and that’s okay. It is what it is because that’s the price that comes with applying whether it’s to an HBCU or PWI.
I’ve applied to plenty of PWIs too, but I can be transparent too because whenever I’ve sent an update regarding my app, I’ve gotten responses confirming receipt of said update that didn’t take nearly 1.5 month to receive. I believe that’s the frustration many HBCU applicants have, in addition to the fact that Howard is one of the very few programs that does not accept the AAMC FAP as a form of payment when submitting their secondary.
