UC application mistake

After submitting my applications I noticed I had accidentally added eng 10 h to my freshman year.It was a slight mistake, I also didn’t mention a couple extracurricular activities I was in. I have sent an email to docs@apply.ucsupport.net, but I would just like to know if these mistakes will affect my chances of being accepted? For educational prep programs I didn’t add AVID and MESA.

No, just keep any documentation received regarding the mistakes in case there are questions later.
