“so mostly AP scores are important for the top tier schools in regards to admission”
^^
No. that would be making an assumption that cant be verified.
We really dont KNOW what is important to top tier schools re AP scores.
Follow what Stanford says they look for. Its wont be that much different from what other top schools want.
After all, top tier schools receive applications from 10X’s the number of students than they can admit.
And admittance is Holistic at all of them.
As Stanford says- the student with the most AP’s doesn’t automatically win.
