hey I'm an accepted student but just wanna say that I was waitlisted at first and it took them 7 weeks to give me the A! I was going to write a letter of interest but I ended up getting the A before that. Unless you've been instructed to not send one, I think this week is a great time to send a letter of interest/intent. Waitlist mvmt for DO schools seems to kick in a lot around mid-May which we're not quite there but approaching. Best of luck!
