ACT test scores for UCI and other UC's

I’m not sure if my ACT test scores are a problem for UCI since I have taken two and the composite scores were the same. According to UCI they will use the highest ACT composite score from one sitting. Should I be worried if I prefer one sitting over the other despite the same overall score? (only one exam date is present in MyTests)

Also, I have made a mistake when self reporting my first ACT score in my reading section while filling out my UC application -supposed to be a 28 but reported it as a 27. Should I overlook this mistake since my official reports state the proper score?
Thank you for the help!

If you sent both score reports, then UCI is probably showing the report in which they will base your admission decisions on, not your preference.

Also, the UC’s will go by the official score report if you made a mistake.
