How much do APs actually matter in admissions

There’s always exceptions to the rule so consider the answer below “general guidelines”

Colleges want to see (and admit) students that are stretching themselves. If your school offers Standard/Honors/AP level classes a student that gets a B+ in AP is going to be looked on more favorably than someone that gets an A+ in Standard (even though the GPA impact is ~ the same).

You don’t state in your original post what grade you’re in. If you’re currently a Junior the college is going to be making a decision based on very little (if any) Senior year grade information - depending on how you apply.

Good AP scores in general education courses outside your prospective major will allow you waive courses and get slightly ahead in college. Good AP scores in courses around your prospective major will generally allow you to take the next level of difficulty course.

You need to start with what AP courses your school even offers. Some offer a lotof them, some none. If you’re unable to take any because your school doesn’t offer them it will not be looked at negatively by a college since they get a school “profile” that tells them all this information. If your school offers a lot of them and you don’t take any it will limit your ability to get into a competitive school and/or program.
