Can I apply to multiple campuses?
No. You may only apply to one campus and select one or two cluster options within that campus.

Can I apply if I have attended COSMOS before?

How do I know if my high school class meets the cluster prerequisites?
Since admissions decisions and clusters are administered at the campus level, don't hesitate to contact the campus directly for any questions about prerequisites. 

How to submit the application fee?
The application fee is payable only in the Parent/Guardian Portal ONLY.  Parents will be notified by email to create a login and password.  They can then make payments, submit their electronic signature (and submit optional financial aid information).

I applied last year. Can I use my same login ID?
Yes. You will need to create a new application each year, as the application may vary yearly, but you may log in with the same account.

Is the application fee refunded for incomplete or non-admitted applications?
No, the application fee is non-refundable.
