What EC's did you take that helped you get admitted? Did you take 2 or less EC's and still get in?

I just want to know because I want to apply to some UC's (UK student), my priority is UCLA. I don't do any ECs but I used to be on a Netball Team. I only do Air Cadets which is based on being in the RAF and military, do you think that will help my chances? I also plan to do horse riding ( haha!)
