<p>I applied to upenn for early decision. It was my only early app. Say I get accepted for early decision. Can and will upenn take back the decision and reject me if I have 4 A's, 2 B's, and 1 C? (C in AP Calc AB, B's in AP Macro and AP Bio) or do you think they would wait for my final report to decide? Are there many cases in which an early decision was revoked because of midyear reports? because of final reports?</p>
