Extracurriculars/Chances

So I am hoping to apply to ISP at Northwestern, but I was a bit concerned about my extracurriculars. A lot of my extracurriculars are very science and math related, like research or science teams. I am worried this will negatively affect me at NU, since they seem to be heavily pushing the diverse knowledge theme. Other than that, my stats and grades are pretty good, I have a 2370 SAT, with a 4.0 UW and a lot of AP classes. Can anyone estimate my chances at Northwestern, provided I have decent, yet not stellar essays.
