It can help to look at the broad view, not just one student, nervous about chances, or one college. This responds to the chances complaints:
I hate to say it, but too many kids don’t really put their own best foot forward, as it is. Partly, their age, partly this rush to the top (applying to so many, hoping to hit pay dirt as high as they can, rather than a more carefully selected lower number of appropriate targets.) Partly that high school has become more competitive, for many, and the kids misunderstand the qualitative aspects of holistic.
So this idea they have to apply to more, because more kids are and their chances go down, is a false understanding, incomplete.
The real first question, repeating myself, is: am I truly what this college wants? (As opposed to, am I tops in my hs or see myself as a snowflake.) If you can’t view it that way, at least in part, chances are you aren’t making your best shot, won’t see an RD admit.
Not because there are so many others applying, but because you, yourself, didn’t present in a meaningful, competitive way- and they found their other 2000 or more kids who did.
Yes, parents help. But many of those without that are being mentored and clued in by great teachers, savvy GCs, and established community organizations. There’s a lot of ground between support from savvy parents and no support at all. And the brightest listen and process, strive, any SES.
