I was accepted into UC Davis however, I only sent in my first SAT score of 1160. I sent this in immediately after I took it to get it sent for free. I later took the SAT again and got a lower score 1130. I never sent this score in so my question is, when my transcript is sent and they see this can they take back their offer?.. Also I took 2 TA classes but when filling out the application their was never an option to show those classes so I never even mentioned it, this will be seen on my transcript can they take back their offer due to any of these reasons???
The UC’s do not allow for score choice. That could lead to a review of your app (but it is 30 points, so highly unlikely). I would contact the school immediately.
As to the other aspect, I don’t think it will hurt your app to have not listed classes, but you should email the school.
Seen the TA classes are not a-g courses, it should not matter if you do not self report. Regarding the SAT scores as @yonceonhismouth stated contact the school and see what they say. Posters on CC can only guess, so it is best you get the information directly from admissions.
