Hi. I am an 8th-grade girl applying for the schools mentioned above ^^. I’ve asked this question before, but I am now further in the admissions process, so I have more information.
Academics:
I’m in a program where most of my classes (except for P.E. and theatre) are 2 grades above. So that means I’m taking Geometry/Algebra 2, Latin 2, etc. My Language Arts grade is a 100, my social studies grade is a 99, my Science grade is a 94, my Latin grade is a 97, my Health grade is 100, and my math grade is a 90. I know my math grade is not the best, but my teacher has exceedingly high expectations!!!
Test Scores:
My overall score for the SSAT is a 94. Math: 95, Reading: 97, and Verbal 80. My essay was pretty strong, but personally, I think I could’ve been more detailed.
Soon I will be taking the ISEE, and I will probably update with my scores from that.
Sports:
I have been playing Field Hockey for 4 years, and am currently on a club team. I will probably continue playing in high school and maybe college.
Extracurriculars:
Piano - I’ve almost been playing for 9 years, and have won multiple regional awards. My piano teacher trains college and professional level pianists, so it is pretty intense. I will continue to play piano in high school, taking private lessons, and maybe joining some type of club.
Voice- I’ve been singing for about 3 years, mostly classical and musical theatre, taking private lessons. I have done performances in my community and have participated in Summer/weekend singing programs. I will probably join chorus in high school to continue this activity
Community service- I’m a member of NJHS, and I do about 10 hrs of community service each semester. I like to work at animal shelters, habitat for humanity, and I do environment-protecting projects. I think it will be pretty easy to continue this in high school, especially BS’s because they have so many opportunities.
Languages/Background:
I am mixed; half German, half Chinese. I speak and write both languages fluently, and travel to Germany and China very frequently. If I got into any Boarding schools, my parents would be able to afford the costs, but it would still be considered a pretty big investment for them. My parents applied for financial aid, but doubt that they will get much financial support because it is not necessarily needed.
I know that Andover and Exeter Both offer Russian programs, which is something I would definitely take advantage of, and also have exchange programs which I would also participate in.
I live in the South, and I’ve heard that I have sort of an advantage because of that.
Interviews:
All of my interviews went pretty well; most of my interviewers seemed interested in me especially those of St. Paul’s, Exeter, and Andover. They would always tell my parents that I had a big personality.
I know admissions can be very unexpected, and there are many unknown factors that go into the decision process. But based on the things I have listed, what is your opinion??
you dont need the ISEE.
If you didn’t need financial aid, why did you apply for it?
I know a family with a daughter similarly within your cohort. She had all qualifications to the schools she applied to, and her parents had a very high-income bracket. However, due to last minute indecisiveness, they applied for financial aid. Got wait-listed from both schools. I think that you have automatically just lowered your chances by financial aid 
Otherwise, theres still always hope! Also I add to @Center and agree with him, ISEE is very unneccesary - focus on your essays right now.
If we got financial aid, it would still help us. We are also planning on sending my younger brother there in a few years which will also add on to the costs.
From my understanding, if a school sees that you can pay full tuition, they will not give you financial aid. In fact, I have heard of some excellent students who were rejected, because of foolishly asking for FA, when they had plenty of money.
