<p>So I was wondering what gpa do Cal state university use. The 9th-12th grade gpa or the 10th-12th gpa? Also, do they use the weighted gpa or the unweighted?</p>
<p>All CSUs calculate your GPA using all a-g courses completed after grade 9, weighted. Cal Poly SLO includes your grades from 9th grade.</p>
<p>Here is the CSU high school GPA calculation:
