What are my chances for Dartmouth

I’m looking to get into Dartmouth, and I am class of 2017.
GPA:3.9/4.2
Test scores: ACT 34(36 reading, science 35 English, 28 math)
I’m working to improve my math score. I have gotten a 31 on math before, making my superscore a 35.
APs: Chemistry, US history, English(I would like to take more my senior year)
Extracurriculars: I was on student council my freshman and sophomore years, and played JV soccer during then too. I have been in Latin club and Chemistry club during high school, and I was in accepted into a summer leadership class the summers after my freshman and junior years. I am expecting to get into national honor society, and I was a runner for a law firm last summer, and expect to be this summer as well. I may get national merit, as I have a 1390 PSAT score with a 209 NMSQT, but I don’t know; it is too early to know.

I know that my extracurricular are a little weak, and I’d like to improve them. I also am working on improving my ACT math score, I am starting to go to a tutor for it.
