What are my chances to UC Berkeley and UCLA?

with 6 Bs in 10-11 you’re looking at a UC weighted capped GPA at around 4.05. For UCB CoE especially in EECS is unlikely, or a high reach at best. Same for UCLA EE. You would have to have some really really compelling essays and ECs. Your stats are good but you are competing against hundreds who have a similar SAT score with 4.0 unweighted GPAs.
