<p>I have read and my son’s counselor confirmed that many universities (and UC’s are at the top of this list) do not accept D’s and you are expected to “make them up.” I think you ought to go to the UC website to confirm this. If you face rejection again this year, I strongly suggest you receive counsel from either admissions people from the universities you want or from a knowledgeable counselor whose trade is in college admissions so that you are not making decisions blindly.</p>
