If you are a current HS Senior, you do not have the transfer option. You are a Freshman applicant with college credit.
When filling out the UC application, you have 3 options for applicant level:
**Freshman- currently in High school
Or Graduated High school but not enrolled in a regular (non-summer) session at a college
Transfer- Graduated High school and enrolled in a Regular session at a college or University
Other- Already have a degree BA/BS or not working towards a UC degree.**
Since you are still in HS, you would select Freshman.
If you want to apply as a Transfer, then you plan to graduate Fall term and enroll at your CC for Spring term???
