Do I need to send official transcripts?
Official transcripts will be required of students who are admitted to the program. They will need to be sent by the acceptance deadline. The best option is to email the official transcript to the campus you will be attending. Please see below.
What are official transcripts?
Official versions are often sent directly by your high school counselor or registrar through regular mail to the COSMOS program you are applying to (details provided in the application). Your school may also give you an official version of your transcript inside a sealed envelope for you to send yourself. If so, do not open this envelope; it must remain sealed to be considered official.
Where do I mail the transcripts?
You must send transcripts directly to the COSMOS program you are applying to. Official transcripts will be accepted via email but must be sent by a school official from their school email address to the correct campus address listed below.

Do you accept electronic transcripts?
Some schools use an online service like Parchment to send transcripts. These online transcripts are accepted as official if sent from your school to COSMOS. The Parchment site will let you know whether your school uses this service. If not, you must order them directly from the high school registrar or counselor. Plan to order these early in the application process or even before. Late transcripts are not accepted.
What does "postmarked" mean?
Official transcripts (see above) and check payments must be at the post office, stamped, and mailed by the deadline. The post office (not necessarily COSMOS) must receive the materials by the deadline. Check your local post office for business hours.
Can I use Unofficial transcripts?
Unofficial transcripts must be uploaded to the application as a PDF before submission. They must be generated after the date the application opens.

For all credit card payments, a 2.5% transaction fee for each transaction applies. The transaction fee is charged by the third-party processor, not COSMOS, and is not refundable even if the payment to which it relates is canceled, refunded, credited, or charged back.
University banking policy dictates that we assess this charge separately from the deposit and tuition payments. Thus, you will be asked to submit two payments: 1) tuition and/or deposit and 2) the service fee.
If you choose to pay by credit card, you must submit both the payment and the service fee before the stated deadlines for your admission to be complete. Alternatively, you may choose to avoid the service charge by mailing a check or money order, postmarked by the stated deadline, to:
University of California
PO Box 989062
West Sacramento, CA 95798-9062
Make check or money order payable to "UC Regents" (not COSMOS).
Please note on the check to which campus you are applying, i.e., COSMOS UCD, and include the applicant's name.
