I feel left behind since many of you guys were smart enough to get your letters prepared earlier in the game. How much time should I give a professor to write a letter? A professor I've asked for a letter, is teaching summer session, which won't end until Sep. 2nd. I was thinking of giving the professor unit Sept. 10th, but is that too late in the game? I was thinking I could have a few secondaries mailed in by then and thus send out my letters as soon as I can after Sept. 10th.
