另外columbia不会通知所有的其他学校,没有哪个学生值得学校花精力这么做吧?这是你自己的commitment. if you choose to break it, you break it. 损失钱,走人, 没人会哭着喊着拦着你。就像离婚一样,被骂得再厉害,你也可以离的。你可以说是你结婚的时候没想清楚,但很多人还是想好了再去结婚的。
If admitted(just IF), and I definitely still want to try other schools........
But not sure if I finally chose another school even after paying for the deposite, will Columbia tell other schools and eventually I got nothing to go?
I was an admit last year, i chose another program over CBS (I turn down MBA for a JDMBA program tho) and no outcome. I just noticed the adcom about it. (Actually I still keep in touch with them and they are friendly to me even tho I didn't join them) You'll just lose the deposit if you have already deposited. The school is not going to notify other schools because basically you don't need to tell them which school did you apply other than CBS.
Early decision traditionally has a better admission rate than other rounds, that's for sure so it is good if your first choice is CBS.
