Denying Admission Once Accepted?

<p>I got into Drexel with a 3.9 GPA and a $15,000 scholarship my junior year. During my senior year, I got an F in one class and got relatively low grades in some others (like Bs and Cs)</p>

<p>Will Drexel revoke my admission? Because its too late to agree to enroll in any other college I got into, and if Drexel revokes me then I can't go to college.</p>
