<p>i have a feeling rescinding admissions are also on an individual basis. The top schools all ask you to explain your grades and if you can explain your grades well, they won't rescind you. A girl that is going to yale called them and they pretty much said that she would have to commit a felony to get rescinded. Not a whole lot of people are rescinded every year (1-2?). A C or 2 wouldn't hurt you too hard if you are taking very challenging coursework. Now when you venture into Ds and Fs.... thats when it starts hurtin.</p>
