What are my chances of acceptance as a junior level applicant one year after high school?

Thanks for the reply. I already sent my application in a month ago. I finished all of the IGETC requirements, and all of the assist.org requirements for UCLA. It’s really my only college of interest. If I understand correctly, the assist.org classes are requirements for application consideration, not merely a competitive edge, right?
Oh, and I applied to UCLA, UCSD, UCSB, and UCB
