Entering non-dual enrollment college courses on CalState application

Help please! Does anyone know how to list college courses taken during high school that are not being used for high school credit on the CSU application? As far as I can tell, the application has instructions for listing courses that were taken to satisfy a - g requirements, but not for courses that are not being counted towards high school graduation. My son took a course that could have been used for a - g, but he did not want it used for high school, and it is not on his high school transcript. I find it hard to believe that CSU’s would not be interested in knowing about college courses taken and grades received unless they counted towards high school graduation. There was a place for entering the names of colleges attended, however.

Well I spoke with one of the CSU admissions people and was told that there is only one way to list college courses on the CSU application and to do it the same way as if it were a dual-enrollment course. You enter the name of the college and the number of units taken and the GPA. Then when filling in the high school courses, when you are in the subject area for the college class, select the college and then enter the college class taken along with the grade.
