from what i hear, it seems like the very competitive schools do not have rolling...so i guess theoretically it doesnt really matter when you are complete...i hope this is true, because my lor's wont be in until october =/
no offense, but i doubt anyone is going to go through the trouble of listing every school. look it up for whatever schools you are interested in. i am sure you can find this info in the MSAR.
i got an email from yale today...theyre not rolling and say specifically it doenst matter when youre interview is, you wont be at a disadvantage for interviewing late
