good rule of thumb is that in addition to the electronic application you submit hard copies of everything. for example:
- dental school transcripts
- undergrad transcripts
- NBME score
- NBDE scores
- Hard copies of LOR's (signed on back)
- application fee
- 2X2 photo
- cover letter listing all of the above mentioned items
additionally, if they didnt ask for your undergrad transcripts (just as an example), the secretary will just toss them. NBD
