Hello! I have recently submitted my CSU Applications and upon submitting them I realized I let a mistake slip by on the coursework. 
My school runs on a quarter system that converts into a semester system as we are only given 2 grades for each class per year. Therefore, my transcripts only show my semester grades. However, when applying, I made a mistake by inputting my quarter 1 and quarter 3 grades (irrelevant grades that only serve a purpose for me and to see where i stand during the school year) for my history course section into the Summer 1 and Summer 2 semester sections, I was only supposed to input my grades into the fall and spring semester sections. Therefore, it now seems as if I have taken 16 semesters of History instead of the 8 that I will have completed by the end of my senior year. Can i fix this? If not possible, how will this affect my chances of getting accepted into my universities?

I guess they would understand what you meant on the app.
