It’s not the percentile in an underrepresented state, but where the score puts you in the applicant pool for your own target colleges. After all, you’re applying to a college with its own structure and expectations and often, highly qualified peers, once there.
And the only “extenuating” that really helps is when classes are not available. But the very nature of homeschooling, incl your case, is you’re online for classes. That can mean virtually unlimited choices.
Whenever adcoms comment positively on something, all kids need to consider that tentative. Each applicant has a full package to present.
Other languages you’ve got some/any proficiency in don’t replace actually taking those courses. Many otherwise strong candidates get dinged for dropping their foreign lang studies.
And don’t assume any tippy top is particularly “great” for homeschool admits. It’s great for kids who knock adcoms’ socks off, considering the flexibility HS kids have in their curriculum choices and the sorts of addl experiences the best of them have accrued. It’s still crazy competitive.
Make sure you know what your reachy colleges look for, as much as you can.
