<p>I requested for a change from RD to ED last week but so far I haven't heard from the AO. I'm a bit worried now since the deadline is three weeks away... Should I call them to confirm my request?</p>
<p>I think I might have taken your call last Wednesday, but just in case that was another applicant, you should go ahead and call.</p>
<p>Thank you very much, I think that was me. </p>
<p>I've received a reply from the Admission Officer and mailed my ED Agreement.</p>
