Chances for Exeter, Andover, Deerfield, Choate, Ethel Walker, Miss Porters (+Thomas Jefferson HSST)

Hello. I’m currently attending a private middle school and am in the 8th grade. I have a solid all A report card which I have maintained from the 5th grade. I do many sports and am on a national sports team (junior/youth) for track. I play soccer, volleyball, track, basketball, and lacrosse. I recently got my SSAT scores back, which I got a 2196 on (91st Percentile) I do many extra curriculars, such as Drama involvement, taking Spanish and doing a study abroad program, achieving high scores on the National Spanish Exam, ranking nationally on the Wordmasters Challenges, participate in Model UN, do Math Counts, have experience with public speaking and have taken some classes, and was a Daughters of American Revolution Writing Contest division chapter winner. I want to know my chances for getting into the schools I listed in the title, which are all the schools i’m applying to. What are some things to focus on in my application process? Any things to highlight that would make me stand out? What do you think helped you get into those schools?
Also, Im confident in my recommendations and have never been suspended or anything of that sort.
For TJ, I’ve been taking prep classes, and have been reaching the 60/100 minimum with the 30/50 minimum for math as well. Im taking the test in about a week, but wanted to ask, what current students or TJ grads have to say about their TJ experience. If I were to get into TJ, I’m not sure if I would attend, only because of things I’ve heard, so Id like to know what people who have experienced it would say. Is the workload potentially “too” much? Does that workload and the focus on maths and sciences hinder students from developing new interests and extracurriculars, which would make the college admissions process harder in terms of standing out? If one wanted to study literature per say, would they have adequate resources to do so (meaning are the classes related to english and history as rigorous as the math and science ones? Also just wanted to know more about your experience and recommendations.
thank you
