Yet another EC question

<p>I have seen many people say you need to have focused ECs and have leadership as well, and this is my case. I am going to be volunteering at 2 hospitals and I enjoy working with the patients and I just really like the environment. Also, I a am a member of Key Club, and probably will join one or two max other clubs if they draw my interest. (The problem here is that due to budget cuts, my favorite club, a science club, was cut. We only have 3-4 clubs left.) I may also do Track for fitness and competition. If I am applying to top 20s and ivies (altho my main hopes lie with either Brown PLME or TCNJ's combined Med Prgram), what kind of impact/effect will this have?</p>
