Keep in mind, you are from the bay area where competition is fierce and if you read the individual 2024 UC campuses threads, you will see there are a lot of unhappy parents complaining about their outcomes.
And sorry, but the top six UCs are not a match for anyone: UCB, UCLA, UCSD, UCI, UCD, and UCSB. Just read the post about an angry mom complaining about her son admitted to Stanford for REA but didn’t get into UCD and you will see.
Do the best you can with classes and engage in activities you like and see where that takes you in 2 years.
Best wishes.
