I emailed them and here were their responses:
From UCInfo: “You are unable to update any courses or grades prior to Fall 2014. You can make a note of the courses in the additional comments section and it will be fully reviewed with your application”
From Docs: “Thank you for contacting the UC Application center. Your changes will be entered in the system and made viewable to the campuses you applied to.”
Still waiting on UCLA/Berkeley’s responses; would you guys suggest I still follow UCInfo’s reply as a precaution?
