For those on the deferred list (myself included), I dont think we can expect to hear back until May. They have one more round of interviews to review (March group), meaning one more round of acceptances will go out in early April. Once all of the acceptances are out, its a waiting game on Tufts part to see which students will ultimate accept the invitation. Assuming that there are a fare amount of students who will ultimatey chose other locations, that should free up spots and they will hopefully start sending out invitations off of the deferred list anytime between April and mid/late May. I believe AAMC sets a cut off date of May 15th where students can hold multiple offers. In other words, by May 15th, if you have more than one acceptance you have to choose one. Given that date, I would assume that a majority of the movement from the deferred list would occur on sometime in May.
Despite the words in the letter, which state that deferred is not the waitlist, I think we have to be honest and recognize that its the same song, just a different dance.
Happy waiting to all those on the deferred list
