You don’t get into a tippy top based on gpa. You can lose out for not continuing foreign language. The competition is that bad.
The only exception I’ve seen is kids who stop FL to fit in quite advanced math or sci- well beyond AP.
If you want a tippy top and think the tip is val or gpa, you are way behind. It suggests you don’t have an idea what matters to those colleges. That won’t help you one bit, can be an issue.
If online lang us accredited, sure. Fine. But I agree AP CS is not necessarily wise, is often low level. You can learn as much in your own. Or more.
