The same way you'd compell him to do X educational task if he hasn't graduated? You could also try to convince him the value of "sharpening the saw" (to quote Stephen Covey) or find a mentor to do so.

@GilWhat about making early graduation conditional on spending X hours per week on education (not necessarily college, could be reading from a booklist)?

Ah, the Regents...

Is he doing precalculus with AoPS? If so, you might want to look into the AMC 10. Intro counting probability + intro number theory (+ intermediate counting and probability) are more than enough for a class; he could probably cover AP statistics in a comparatively short period of time if you wanted to add that (if you ask Daijobu nicely I'm sure she'll be happy to share her AP statistics material). For science, if he's taking calculus next year, he could also take calc-based physics using a book like Halliday, Resnick, Krane. For chemistry, Clover Valley Chemistry offers live and self paced advanced honors chemistry classes.

I've seen good reviews for this on the board; I'm surprised I haven't seen this here yet: https://www.fundafundaacademy.com/product/biology/ @Dicentra

They might not forget what a derivative or integral is, but if they memorized the chain rule or integration techniques by rote (as most do), then those are likely to be forgotten if not practiced.

@TheAttachedMama

Check out the UAlabama Presidential Elite scholarship. It's a full ride plus extras, but would require a 36 (non superscored).

Where did she do AP CS A and AP statistics?

One other thing to consider, is that if the last time he does calculus is in 11th grade, he will be coming in to college rusty, which could be a problem if he starts with a class covering new material

It's like physics: you can take calc-based stats or non calc-based stats. Unlike physics, though, calc-based statistics is rarely taken in highschool so you might have a hard time finding stuff beyond textbooks and online lectures

Algebra and trig, but to a deeper level, covering exponential functions, logs, and complex numbers. Trig is not a prerequisite for precalculus. If you're not sure whether his background has him prepared for calculus, many colleges have public calculus placement tests which cover precalculus material. Here's an example: https://math.indiana.edu/documents/Sample-Calculus-Placement.pdf

How did it approach MLE?

What does he feel the major positives of homeschooling would be for him?

Do you mean https://www.synthesis.com/? How long were you on the waitlist?

According to prepscholar, it opens in the last week of July for the entire upcoming year including next year's July date. That would also explain why this year's July date was full; people have been registering for it since last July.

Many of the later Magic Tree House books (Merlin Missions) are at a higher reading level and intended for older readers

I've heard Halliday Resnick Krane recommended for students interested in f=ma and USAPhO due to its level of depth and challenge problems

Try Uncle Tungsten as well

Which one?

Checkout newsELA. As a kid, I found news unengaging because it tended to focus on politics, which felt like distant grown-up drama to kid me. If you want your kids to get the sort of general knowledge a news-literate person might get, consider podcasts like planet money, hidden brain, and freakonomics

Do you know why that is?

Which others stuck out?
