High Match is less chance than a Match school but not a Reach school. ED could help your chances.
I am positive that Cal Poly SLO uses 9-11th grades in their GPA calculation.
This is from the Cal Poly SLO website:
Academic Performance
College prep GPA Calculated by Cal Poly for 9th -11th grade coursework designated on the application (with honors points granted for courses designated as “honors,” “college,” “advanced placement" or “international baccalaureate” on a high school transcript, for up to eight semesters).

All other CSU’s only use 10-11th grades, since 12th grades are not available at time of application.
