Hello!
I submitted my apps already, and on it I listed AP Statistics (through UC Scout) as one of my courses.
This was not recorded on my school transcript by my counselor.
However, I did not finish the first semester of the course on time 
Will this negatively impact my admissions? Is this even worth notifying colleges about? I was mostly doing Stats for fun and it was not on my transcript or official HS report, only the Common App self-reported course section.
For reference, I’ve applied to all the UCs, Middlebury, Pomona, Occidental, and WUSTL. UCs have not emailed me for senior year grades so I was not planning on mentioning this to UCs now.
Thank you for your advice.
UC’s do not ask for Senior grades but if you listed the class on your UC application and do not complete the class or drop the course, you need to notify them.
Freshmen: If you change schools, add or drop a course, or fail to earn a C or better in a course after you submit your application, you must notify the UC Application Center by email or postal mail. Your correspondence must include your name, UC Application ID number and your signature (if you mail a letter), and will be available to all the campuses to which you applied.
If you receive an offer of admission, be sure to confirm with the campus admission office that they are aware of the deficient grade or schedule changes. Although you must notify the campus of these changes, we cannot guarantee that a campus can go back to review an application after correspondence has been received. Make sure to save a copy of your correspondence just in case.
