Calculation of sGPA for Optometry School

Hey guys,

I checked on the forum and online, and couldn't find a specific answer to this. I know for premed its pretty straight forward how the sGPA is calculated, but how is it calculated for optometry school. For example for optometry, would a math class like College Algebra, be a part of the sGPA calculation? Or is it only specific math classes, rather then all math classes that an individual took?

Thank you
