I’m a Dartmouth alum. I’ve been doing admissions interviews for 30 years. At Dartmouth, alumni handle the interviewing process. I’d say you have a very solid shot. Hate to say it, the high scores and challenging coursework is key. But, it’s Dartmouth, so they are looking for much more as well. Character is important. Your figure skating is a singular talent, and Dartmouth offers lots of ice! Try to broadcast things that you’ve done/accomplished with your talents that have made an impact beyond yourself. There is also a “Dartmouth women in science” program that someone with your interests and aspirations should look into. You can investigate via online. Dartmouth is also adding graduate students to these departments which will broaden your experiences in STEM classes (IMO). In addition the climate will make research opportunities for undergrads more cutting edge. My son recently graduated and I serve on a few boards up there, so my recon is current. It’s a fantastic school. Dartmouth is quite special, but keep in mind there are other great places to get a great education. What you end up bringing to a campus (your intellect, curiosity, enthusiasm, open-mindedness, sense of adventure, etc.) is always more important than the institution. Though the institution can be the frosting on the cake. Best of luck!
