although having your FULL application at each school prior to taking the DAT may sound good in theory, *most schools will not look at that application until your scores arrive
my story:
july 2006 dat scores and rest of application sent to schools in the first aadsas mailing, while retaking the dat on oct.2 (same TS and AA as 3 years prior)
2 pre dec interviews (one bc they were only schl to look at prev scores and the other school offered me interview following communication with them just after receiving my new scores)
not too come off as pretentious, but i believe there would have been about 2-3 more interviews (BU, buff-instate) offered to me had my DAT been taken 2 months earlier
what i stress the most when offering dental apps advice is timing, bc if anything is off key (transcript, lor, dat), you are severely jeopardizing your chances of being interviewed
i consider myself extreemly lucky to have gotten that second pre dec interview, if you ask me, oct, sept and even aug dat takers are somewhat late and pending the school, risking their shot
