Edit your essays if they are simply “decent”. These schools don’t want decent kids, they want kids who are, for a lack of a better word, awesome!! If you know that you could do better on your essays, go for it.
Your SSAT scores are already great so that won’t take you out of the running.
Your extracurriculars are great but what do you “spike” in? What are you passionate about the most?
Do well on your interviews because really boosts your chances of being admitted.
All in all, your stats are great but remember, there are hundreds of other kids with similar stats applying for the same spot, so you might not stand out very well. It all goes back to your essays. Your essays are a crucial component of the admissions process.
Also, are you an underrepresented minority? With those stats, your chances are huge.
And out or curiosity, is the reading portion of the SSAT as egregious as other people claim it to be?
Try to show some leadership in Awards and ECs. Polish your essays, and find something unique about you to stress in your essays. Good Luck! Remember the old boarding school adage however if you don’t get in, “The school doesn’t make you, you make your school!”
Short answer…maybe. Nothing you posted takes you out of the running, but you know the acceptance rates. Polish every aspect of your application, write GREAT essays and hope for the best.
