When reapplying do you have to resubmit everything again to AADSAS and the schools? By everything I mean Letters of recomendation and transcripts. It would be easier if they'd just hold on to the stuff from last year.
But check with your schools first. I know that at Temple you dont have to reapply through aadsas. All you have to do with them is send them updated transcripts and and the application fee.
...Also, they (the dental schools) would like to see you improve on your applicant essay, as well as one or two new letters of reference from other professors.
