Do LORs need to be in any particular format; addressed to each school, LSAC? How long should they be (roughly)? I understand you should not fill a paper with empty words, but how concise is too concise?
Also, is it important that the letter actually say somewhere "letter of recommendation"? I had one recommender put "in reference to: my name", "asked to serve as a reference," etc.
I'd appreciate any input. Thank you!
