UCLA and Berkeley chances?

Currently I am junior and I have started to really look into colleges and the chances that I have at them. Two of my dream schools are UCLA and Berkeley and I was wondering what programs, internships, or activities I should do over the summer transitioning into senior year that I should do.
Here are my current statistics:
Rank 2 of my class
4.15 (W) 9-12
4.38 (W) 10-12
300 hours for community service at school
Clubs (with leadership positions) such as Red Cross and National Honor Society
This summer is going to be very important one in order to finalize my application and I was wondering if any of guys have tips on what additional things I should do outside of school in order to help my application. Should I join my school’s ASB? Should I take on internships for hospitals?

Please calculate your UC GPA and post Capped weighted and Fully weighed. How about test scores? Intended major?

Leadership positions look good on your applications along with community service. If you are leaning towards the Medical Field, having some first hand knowledge in a hospital setting can help you focus on your eventual career goals plus it will add to your EC’s.
