I’m a 8th grader applying to 9th grader, so of course, I can’t exactly chance you. However, I will say, your passion can clearly show through your extracurriculars, with is amazing! When it comes to boarding school admissions (or admissions for any kind of academic institution), boarding schools are trying to predict who might turn out to be really successful and give back.
Students with a clear passion (and have already started pursing that passion) is exactly what they are looking for. So congrats on that part.
I would work on continuing to develop your passion throughout all your application material, shaping different parts of your application to contribute to the main narrative. For an example, if I want to be a journalist, then my essays should focus on different skills that show I would make a good journalist. Your recommendations can zoom in on different parts of your personality that can further this narrative. A good way to go about this is to maybe take a piece of paper, write your passions in the middle, circle it, and create a mindmap of different qualities you need to be successful in that passion.
One last piece of advice- apply to schools that you will genuine be happy at, because let me tell you, they can tell if you would be a good fit. That means not just huge schools. There are so so many amazing schools that have amazing programs that fit your needs, and still send quite a few kids to Ivies every year. Like, have you checked out Kent’s pre-business program…? I think you would love it!

Also Episcopal is literally right outside the US capitol, and has a really cool externship program! I’m an entrepreneur, and at my local high school, there aren’t really any good entrepreneurship classes. I was kinda in the same boat as you, thinking that “What would be the point of spending 200,000 dollars to go to a school that is barely better than my old school?”. Like, I was thinking about prestige. But trust me, you are far better off with a school that understands you and has specialized programs for you. I know I’ll be considering the school schools I mentioned above.
