I am a little confused about the residency application process. I start my 4th year on 6/25/07. If the first date for ERAS is 9/1 (and applying ASAP is ideal), then that only gives me a few months to do audition rotations. My school also requires that I take the step 2 boards before 9/1. What happens if I do an audition rotation around 9/1 or after that date, get a recommendation letter and try to update my application? Is that even possible? If so, how far after that date can I add a rec letter and reasonably expect that the PD of the residency will see it?
