Chances of Getting into Northwestern (Medill)?

Hello all, I just made a CollegeConfidential account and I’m wondering where my chances are at getting into the Medill School of Journalism at Northwestern. I am currently a Junior, so my GPA isn’t set and neither are my EC’s, but here is what my application would be so far.

GPA: 4.0 (I go to the International Academy, an IB school that is consistently ranked as one of the top ten public high schools in the US)
ACT: 33 (36 English, 35 Math, 32 Reading, 29 Science)

Overall, my GPA (especially with my tough courses) and ACT look pretty good for Northwestern. However, compared to other people I see on this website my EC’s don’t look as strong. By the way, the years would include Senior year as well (except for Track) even though I’m still a Junior.

Cross Country (3 years)
Track (3 years)
School Newspaper- Staff Writer (1 year), Sports Editor (2-3 years, depending on my chances at Editor in Chief next year)
BuildOn member (4 years, decent chance at getting on board next year)
Model-UN member (4 years)
FBLA member (4 years)
President of Sports Club (3 years- I know it’s a dumb club, but it shows some leadership ability)
German Honors Society
National Honors Society
Tutor at Local Hebrew School (4 years)
Participating in a leadership class with same Hebrew School about how to become better ‘Madrich’ as it is called (3 years)
Job- Baseball umpire (4 years)

I think that’s it. The reason I think that my EC’s aren’t as strong as others is because I see so many people with a bunch of awards to their resume that I don’t have, and the fact that I am not really on board for many of the clubs I am in.

Overall, I just want some opinion on how I stand for NU admissions. Do my EC’s need work? Should I try for a higher my ACT to make up for it?

Ok to anyone who reads this there is a typo in the second line. I am currently a JUNIOR not a sophomore.
