我也被waitlist了,大家有没有经验分享一下啊?我看到kellogg的网站上有这样的建议:If you would like to provide an update on your candidacy, please submit your letter in writing via email. We discourage the submission of additional letters of recommendation or references from third parties, as we prefer to hear directly from our candidates. 好像不鼓励让别人写额外的推荐信。
