UC Berkeley considers 10-11th grades only in their UC GPA calculation: https://rogerhub.com/gpa-calculator-uc/
I would say just based on what you have posted, UCB will be a difficult admit when they have so many excellent students with top grades applying.
At the end of Junior year, calculate your UC GPA and if you are around the 4.0+ range with competitive scores, then it would be worth your time to apply. Until then, keep working hard and do your best.
