Hey dude,
First of all CONGRATULATIONS!!!! What a fantastic dilemma you have!
In general, Duke is considered a bit better, although Cornell may be a bit better if you want to get into the NY finance scene. It all depends on your goals. What I would suggest to be honest is that you plan yourself a small vacation to the US and visit both schools for a day or three. Either way, you can't go wrong!
2、正如楼上几个人所说的,ithaca冬天很可怕。开车很艰难、很危险。大雪的时候不会封城,但是下山(cornell在山上)出奇的困难;而且大部分飞机会误点(几个小时)或被取消。这对在冬季recruiting的人打击很大。did i mention winter lasts at least 4 months in ithaca? 由于这个原因,很多recruiter也不愿意过来。这个地理位置和气候绝对会影响面试求职。
