It is usually more difficult to maintain a very high GPA at elite private high schools, and university admissions knows this. They will interpret your grades in the context of whatever high school you are attending.
This is very good.
This is also helpful. While there are some universities that do not consider freshman year at all, your sophomore and junior years will be more important pretty much everywhere.
Your guidance counselor will most likely be providing a reference for you for your university applications. They can mention any health and/or family issues that you may have experienced during your freshman year. Your ability to overcome this and still do very well at an elite high school will speak well for your likely ability to do well at an academically demanding and highly ranked university. However, this is something that your guidance counselor can explain.
This is superb.
And as others have said, you can study either economics or biology or both at any one of a huge number of universities. These are majors where a graduate degree is also a possibility. You can get into a very, very strong graduate program after getting your bachelor’s at any one of a very large number of colleges and universities.
To me it looks like you are doing very well.
Okay, so finances will matter.
I am not sure what you mean by n/a. Do you have an expected or known source of funding for the cost of attending university? Are you planning to focus on schools that meet full need?
Do you feel that Stanford would be a good fit for you? I am biased here since I got my master’s degree there and loved it. However, if you think that it would be a good fit then I think that it would be worth applying to, and very likely worth applying REA.
I also agree with others that if you are attending an elite private high school, then your high school guidance counselor will have a very good idea what universities you are likely to get accepted to, and what universities are likely to provide any needed financial aid.
And I also agree that you are doing very well and there is a great college or university out there for you, and probably a choice between multiple great colleges and universities.
