SDN Members don't see this ad. (About Ads) Sorry in advance if this topic has been hashed over on some other threads that I couldn't find. I will have one radonc rec before sept 1. I am scheduled to do another away rotation in Sept but am concerned that it is too late for including a letter in my application from that program. How do the folks in radonc work it? Will they start downloading your application from ERAS only once all your letters are in? Or can you add a 3rd and a 4th letter up to the program's deadline? Would it be worth holding out for a second LOR, or just closing the deal with a completed application?
