@applicant4c, as I keep telling my S18, getting into a highly selective college is not the goal in life. It’s to get a good education that will give you a solid footing for leading the rest of your life. The US is blessed with an embarrassment of riches when it comes to colleges where you can get a great education. Secondly, acceptance percentages don’t signify the top 12.8% or 4.8% or whatever percent of a given college’s applicants, right? They signify a percentage of all applicants. In their push to bring in balanced classes (in terms of smarts, EC involvement, grit, athletes, URM, first-gen, male, female, tough home environments, etc., etc.), colleges necessarily must cast a wide net, not just pick from the top. Which means many kids from the top, the middle and the bottom will be denied.
As one of the other commenters said, I do hope that in the next four years you not only work as hard as you have done in the last four, but you also take time to stop and smell the roses and eat ice cream and read books and watch movies and cook amazing food. Feed your soul as much as you feed your brain. Life is a long haul trip. All the best to you whichever college you end up at.
