I was just accepted today off the waitlist!! I made this account to update you guys because up until today, I was frantically checking this forum (like most waitlisters), and I found people's updates helpful.
I was able to speak to Dr. Morris regarding waitlist movement recently, and they're anticipating people to drop their A's a bit later because LSU is being slow with their acceptances and many in-state people choose LSU over Tulane because of the price. So there's still hope!! (Also, I sent updates, I'd recommend sending one about your summer plans/volunteering if you haven't already)
