You can get into all three except for Brown, Yale and Stanford. Only because they are ivy leagues and unpredictable. Your numbers are amazing but you should focus more on your EC’s and you as a person. I see you want to major in international relations so maybe take out the sports for EC’s and keep the rest to really show you can achieve a degree in that area. Maybe for your essay talk about your trip to Spain but make it reflect you and not sound like the other out country essays others write about which should be easy since you have many writing achievements. TL;DR Your stats and numbers are great but who are you? In the end I wish you all the best I can give (I need some for myself lol) and GOOD LUCK! <3
