Can I get into University of Chicago?

I have 4.97 out of a 5.00 GPA (non-weighted) and a 5.36 GPA (weighted). Currently, for my junior year, my non-weighted is 5.00 and my weighted is 5.50. Out of a class of 538 students I am listed as 33 (weighted) and 18 (non-weighted). The problem is that I do not do well on standardized test. I do not know why (it might be subconscious). On my ACT I received a 26 even though I can get high scores when I am not taking the real one (e.g. non-real math - 34 real math - 29)... This is really frustrating because I would not like U of C to judge me based on my score since I simply stink at standardized tests. I have a lot of activities and hobbies outside of school. I speak, in addition to English obviously, Romanian and French. I am also learn Japanese and I used to learn Arabic, but I put it on hold because I began to mix the languages together. I will also be taking Italian during my senior year and I will continue to learn it since it is very similar to Romanian. I taught myself how to play guitar and violin. I also play many brass instruments since the valve fingers are the same or similar. I also used to play piano and I'm trying to keep that alive. In addition to music, I do gymnastics at school, but I had to stop due to a shoulder injury;however, I hope to join again my last year. I also train for parkour. I do volunteer work at some places,etc, etc etc. I can go on and on but the point is that I feel like my ACT score is a deceiver for U of C and I am afraid that they will not look beyond it. Was anyone in my position and managed to get accepted to U of C? How are my chances?
