Just remember, the “Most Demanding” check isn’t what greases a kid into a top college. Adcoms look at the transcript and get their own read. Getting to, say, 7 AP, when they’re the “lites” or non cores (or don’t include rigor in the hoped for major) won’t work magic. Get a good idea of what the cores are, vs electives. And see what each target recommends for hs coursework. Eg, APES wont replace core lab sci and hs CS courses don’t make up for other rigor colleges want to see.
