<p>Hi, I recently got an email saying,
"Dear ______,</p>
<p>Thank you for your patience while we worked to provide you with the most
accurate information possible on the items needed to complete your Regular
Decision application.</p>
<p>The item(s) missing from your application include:</p>
<p>Evaluation: Humanities/Social Science</p>
<p>If you have these items sent immediately, we will be able to review your
application and make a decision by the middle of March. We recognize that the
items may have already been sent, but for some reason beyond your control, have
not arrived at Caltech. It is important that items you believe have already
been sent be resubmitted to us at this time.</p>
<p>The quickest and most reliable method to submit the missing item(s) is through
the Common Application website. Please have your recommender log on to the
Common Application website and submit their document for you as soon as
possible. It is not necessary for the document to be sent by mail if it is
submitted online.</p>
<p>Please let us know if you have any questions.</p>
<p>Sincerely,</p>
<p>Ray Prado
Director of Admissions"</p>
<p>what does this mean? what exactly am i missing, a teacher recommendation? or did the recommendation have to be one of humanities/social science? I am so confused.</p>
