I like compmom’s post. There are options.
Lots and lots of kids get accommodations. Whether it’s specifically the same as what the hs offered is less important than the right support. Good chance there will be an easier math course or two that fit the grad requirements. And this is a high performer; if she gets a C in some math class, based on legit challenges, my own attitude is: so be it. She’s not on a stem track,right?. (And I already suggested Mom look into the actual course choices.)
The CYA is partly in choosing the right safeties, in case. But the other side, for the more preferred colleges, is trying to present the right picture they want, well beyond stats. (And this definitely applies to test optional.)
In that respect, I agree the hospital work is good. But we don’t know what it is or how much, whether it involves a level of responsibilities or frankly, not. Some of the colleges named will like to see some diversity in what she did (and how it gels,) as an indicator she’s likely to explore/take on various things on campus. And her energy. Maybe it’s additional service, maybe some role in the hs, or other activity. Show she’s engaged, open, interested and can commit in various ways. Maybe she’s got this covered (more than honor societies.) But if not, there’s time to tweak.
Also, look at the Common App, see what they ask and how she has space to answer. Try to start to think in a more holistic and strategic way. What do they want, how do I show it? More than stats. It’s possible.
