oh really, the letter was signed by don martin himself?! anyway, thanks a lot for your encouragement and advise. I have contacted both don martin and kristen pawlowski, my interviewer and the associate director of admissions. kristen has responded and said will assign me a counselor.
Emily, Gowell and 飞雪, thank you very much! Hope I may still have chance to be your classmate commencing from this fall (of course if you would like to choose Chicago GSB to attend)
