I think your resume is very good. Some other users might be saying that you need to be even more “well-rounded”, but I do not agree with this. Your commitment to skating is excellent. People try and be a super diverse person just to stand out to colleges, but the thing is that if you are very committed to an EC, that will look better than jumping around. For example, a family friend of mine has a son and daughter. The son’s application included tons of sports, activities, clubs, classes, etc. The daughter’s application mentioned her personal blog, which has over ten thousand followers. Both had good grades. The son did not get in and the daughter did.
What are your grades/ test scores?
