Education Law Issues: 18 Year Old Enrolling Self into High School

My question involves education law in the State of: California

Hi,
I'm 17 and currently live in Texas. My mom has given consent for me to move to California with a family friend. Am I able to enroll myself into high school when I am 18 without a parent? What about 17?

Thanks
