<p>A bunch of people seem to be wishing that colleges told you exactly how poorly you had to do to get rescinded, but if you think about it, that ruins the entire point of the threat, as then you will do the bare minimum to not get rescinded. A threat without specifics gets you paranoid and makes you work harder. Also, there could be extenuating circumstances so often colleges will first send you a letter asking you to explain yourself before rescinding.</p>
<p>Oh, and colleges can't take away your degree but they can invalidate it, which will make it nothing more than a piece of paper with pretty writing on it.</p>
