I highly, highly recommend CALLING Cal Poly admissions for application questions!!! They are extremely helpful. I called them almost every day for a week about my son’s high school coursework, talked to different people each time (NOT students) who were very consistent in their answers. One even offered to walk through the entered classes with me. I did not wait too long to get a live person, much better than email!
FYI - one admissions officer did confirm that Cal Poly does not use the Achievement sections, but could not explain to me the reason, kind of lame.
