How do these ECs look?

Im an African American Junior. My UW GPA is 3.96 and my weighted is 4.4.

I’m beginning to stress a bit over whether or not I have enough ECs to be competitive for the schools I’m looking at applying to (UC Berkeley, UCLA, Stanford, Columbia, UC Irvine).

Here are my ECs:

9 years of orchestra (cello player, was 1st chair for 7 of those)
Beta Club
National Science Honors Society
Multicultural Club (Class rep)
Mu Alpha Theta
Self taught in Korean for 4 years (Have a very solid SAT II score to prove it)
Attended Tech Trek summer program at Stanford (the program leaders said it would look good on a college app, therefore I am adding it)

I’m very passionate about different cultures, I was thinking I could write about that in my essay to emphasize that.

Tell me your opinions as to whether or not I can me competitive to those schools with these ECs.

Bump, please give any feedback!

Alright… here is my feedback.

The clubs you listed are great and all but colleges (especially selective schools such as UCLA and UCB like to see a few leadership positions)
Your musical position will be a plus as it shows commitment and devotion. (9 years? wow)
The summer program at Standford also is a pretty good ec.

What you need to do is direct some of those ec’s toward whatever your passion is.

(I too am an African american junior! Good luck!)
