It is my understanding that the first day you can submit ERAS is September 1st. I'm not sure what you need to have completed in order to do this. You may be able to submit without any LORs? I think the last day you can change/add things to your application is November 1st. Therefore, you would need to have your LORs written and submitted by then. If this is correct, the latest you could probably do a rotation and get a LOR would be September.Red58 said:My other question is if I do an externship at a place I'm interested in, in October, is that too late to ask for a letter of Rec? Any advice would be very much appreciated.
