When submitting your application for dental school do you need all of your letters finished by the day you apply? How does letter submission work for the dat? I understand I never see the letters but I dont understand how would I submit them or attach them to my application or is there a link I give to my schools committee and other people I have writing a letter? If there is a link and they submit it on their own time, if I apply the first week the cycle opens for submissions then when should I notify my mentors and schools committee to finish and submit their letters by? Should it be the same week I apply?
