I am currently in the middle of submitting my application to med schools for this cycle, however, a medical problem of mine has returned and I may have to delay my application for a year. All of my recommendation letters are dated 2011. Would it be ok to use these letters next year (for the application cycle starting summer 2012). I would probably have a few newer letters to throw in there if this happened... I just didn't know if it would matter to have letters dated from one year ago.
