CSU Eligibility Index

I know that the formula for your EI is GPA800 + SAT score (CR and math) for SAT and GPA200 + ACT score * 10. I was just confused on the GPA portion.
Is the GPA supposed to be calculated as weighted or unweighted?

The GPA is CSU weighted. 10-11th grades for a-g courses. Maximum 8 semesters of approved Honors and AP/IB classes. Here is the calculator: https://secure.csumentor.edu/planning/high_school/gpa_calculator.asp
