Application fee; deposit & tuition

For deposit and tuition fees paid by credit card, a 2.5% transaction fee applies. The Application Fee is exempt from this service fee.  This 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.

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.

DISCLAIMER:   COSMOS is not responsible for lost, held, or damaged mail. COSMOS is not responsible for delivery errors via carrier or incorrect shipping info. PLEASE CHECK YOUR INFORMATION, and do not request receiving a signature upon delivery. Registered mail is strongly recommended.

Financial aid application, including tax return cover sheet or TANF (no social security numbers), must be completed with the admission application.

Upon admission, each campus requires several documents to attend COSMOS.  These include official transcripts, waivers, permission slips, medical information, etc.  Please be sure to review these documents carefully and submit them as instructed.
