<p>I recently got accepted into UPenn, which is binding, and I was wondering if I had to formally withdraw all of my applications to the other colleges in RD or that I don't have to do anything since i'm not RD forwarding through questbridge.</p>
<p>Congratulations on your Penn acceptance!</p>
<p>You only have to withdraw RD applications you have actually submitted. If I’m correctly understanding your post, you had originally planned to have QB forward your app to schools for RD if not matched, but since you’re matched will obviously not being doing that. Therefore, you have nothing to withdraw. </p>
<p>If you have submitted any RD apps to non-QuestBridge schools, you would need to contact them and ask to have your application withdrawn.</p>
