AP Physics 1 or AP Physics C?
Have you taken Physics and Chemistry before?
Unless you absolutely can’t, I’d replace AP English Lit with Honors English, and/or one of the two science AP’s with their Honors version.
One day off can’t possibly be “too much material”, and since your body will be recovered, it’ll function much better.
Are you instate for UC’s? Or UMichigan?
(what’s your state of residency)?
Do you know your EFC and how much your parents can afford/are willing to pay for your college?
Why NYU? (It’s well-known for its stingy financial aid so unless you have a college fund with 200K in it, don’t focus on it too much); if it’s to live in NYC, Fordham is a great choice (with two sites: one with a campus, a quad, etc, in a quiet area of NYC but 30mn from Manhattan; the other, Lincoln Center, is right in the middle of Manhattan but doesn’t have a campus per se.)
What do you like about them? Are you interested in a specific major?
These colleges (and other colleges with that level of selectivity) will expect 4-6 APs total, and a total of 2-24 classes (or so) either Honors or AP (in other words, 14-20 honors classes + 4-6APs).
