From the admissions page:
Please note: AP and IB exam scores will not appear below in the “Official” section until July 15. Also, AP exams with scores of 1 or 2 are not displayed, since they do not earn academic credit. You will be notified if required exams have not been received.
Starting July 15: Please verify that we have received your official scores in the “Official” section below. If you sent multiple exams, only your highest exams will be shown. If your official scores do not appear below, we have not received them. In that case, please call the appropriate testing agency to confirm that your scores have been sent to our office. If the testing agency confirms this information, please contact our Undergraduate Admissions office at (530) 752-2971.
If you are certain you did not put UCD down to receive your official test scores call to have them sent.
