OP, what does your GC say about your prospects at these super-selective schools? Your GC certainly has a better idea of where you are in your cohort, and how students from your school do in admissions at those schools, than anybody here.
I get this: you are in a school that flags itself as a “T-30” private school (which, btw, is not actually a thing), which implies a community that puts a premium on prestige.
If you are marinating in a pond where brand is an important metric, you may not be open to hearing this, but you will do yourself a serious favor by thinking hard about what you actually want from your college experience. Where do you want to be in 4 years? what parts of you do you want to grow and develop? what kinds of environments do you tend to thrive in? do you want a bigger version of your HS or something very different?
You say Yale is ‘minorly’ your favorite- why, exactly? Why these 4? (Duke & Williams are different top to bottom). Are these just the most famous schools on the list your GC suggested?
