My ET’s are:
3 years of varsity volleyball (As captain).
2 years of varsity basketball
2 years of varsity Tennis
3 volleyball clubs outside of school (5 practices a week for 2 hours each).
2 week trip to Nepal for Trekking/Working at a school there.
Over 200 hours of community and service

What are my chances for either UCSB or UCLA?

UCLA will be a tough admit since test scores are below the averages. UCSB could go either way 50/50.
