Application fee; deposit & tuition

As of April 2017, all credit card payments incur a 2.5% service fee.  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 stated deadline, to: 

Cashier's Office
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 UCSD, and include applicant's name.

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

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