Do you have access to Naviance or SchooLinks? Via the latter, I can see detailed school-specific and district-specific data for actual applicants from 2019–2024 down to the weighted and unweighted GPAs of students who were admitted, denied and waitlisted. This will give you a very specific picture of the students from your school who are most likely to be admitted to certain colleges. You’ll be able to see bar graphs and scattergrams of both weighted and unweighted GPAs.
Sounds like you’re taking a rigorous courseload and doing well. You’ll figure this out! As for Cornell, make sure to research all 8 undergraduate colleges: Though there is a central undergraduate admissions office, each of the colleges has ultimate control over its own admissions process and has a different acceptance rate and priorities when it comes to picking a class.
