If your Dean's office doesn't support you, you may find out by e-mail or going to the match site March 17th, 12 noon eastern time. The scramble doesn't start until the next day.
If you signed up with NMRP, you will be e-mailed a list of all the unmatched spots. Some will have phone numbers attached to them, some of them even correct. If you can borrow a green book, or have fast access to FREIDA, do it. (I'd recommend book over freida, searching is somewhat faster and you don't have to worry about FREIDA being overloaded.)
You should have ready:
1) paper copies of you eras application, PS, transcripts, Dean's letter, and letters of recommendation.
2) Two phone lines if at all possible, with the numbers updated on your eras application. A fax machine with cover sheets, and internet access that isn't blocking your telephones, ideally.
3) You may want to consider writing PS for your scramble backup specialties. I don't know if you can add these to your eras application at this time or not.
4) An assistant you work well with while under pressure. It is always great to have an extra pair of hands to fax, search, run to the store to get the large bottle of gaviscon, etc.
ERAS will let you apply to 30 programs without extra charge during the scramble. Check out their web site for more info.
Good luck to everyone!
