DO I have a chance at Elite colleges?

I’m going to phrase this slightly differently.
Can you get in? Quite possible, if you work really hard from now on, get leadership positions in ECs, contribute meaningfully in class so you get really good teacher recommendations, etc.
But.
It seems every year on CC, we see kids who have done all that with the overriding aim of getting into a tippy-top school. But getting into a tippy-top is also a lottery, because at 5% or so admit rates, nothing is guaranteed, It’s heartbreaking to see kids who have worked to the max for 4 years, got great grades and everything …and didn’t get into any reaches, coming on here and writing that they feel they wasted 4 years of working to the bone in high school. Almost as sad was the poster who did get into an ivy …and didn’t want to go, because high school had left her burnt out, and she just wanted to go to a college where she could relax a bit and not have to keep working at maximum pace.
So tl;dr: whatever you do (work hard, join clubs etc) make sure it is stuff you want to do anyway, and that you will look back on your high school years as being happy and fulfilling even if you don’t get into a “dream school”.
