@elise123 You have exceptional scores & grades. The best thing that you can do now is make an appointment with your school’s guidance counselor, explain your family’s financial situation and parental makeup and ask how that would be reflected in the process. Depending your GC’s contact list among admissions staff, perhaps you could get a professional opinion or two on your exact situation, or at least a guideline for next steps.
You’re thoughtful enough to be building the roadmap during March of your junior year with a highly competitive score locked in. You should be ok.
