Look OP, I scored very well my boards and still did not match. I wish that I was advised to rank backups (prelim surg and medicine, and a few cat medicine would have been good for me). There are people in my class that are great applicants who did not match in EM, and they had to SOAP. A few were not able to find positions in the SOAP, and found themselves in a really sticky position (not sure why it's hard for EM and anesthesia to SOAP, but it looks like it was this year).
Things are getting harder for everyone, especially for EM people. You must rank backups. For you personally, I agree with one of the other posters that you may need to rank a good number of IM/FM spots to match there. You could always do a year of IM and then get into EM.
Good luck!
