All of these schools are reaches. I would not recommend Cornell, BU, or Princeton for pre-meds.
You can calculate your uwGPA yourself, core courses only, on a 4 point scale. What are your AP test scores?
It sounds like all of these schools are affordable, is that the case? Are you full pay?
Lastly I agree with collegemom that your essay has to be about who you are today. 5% circumstances, 95% you. AOs aren’t admitting your family members.
I am not sure I would talk about the ethics of fast-tracking a covid vaccine…we really have no idea where we are with this, because there is no vaccine yet and there might not be for a long time.
It would require an advanced level of industry knowledge and deft writing to be critical of pharma vaccine development during a pandemic when literally the entire world is waiting for pharma to save it/allow daily life to normalize.
