Another thought is Early College at Simon’s Rock…for those who have run out of courses at their HS.
You’re welcome @Mommertons , and if he does not watch the online lectures (usually not a requirement) it becomes self-study in a hurry. 
hey Mommertons,
OK so it sounds like your D and my S are roughly in the same boat, but we have a nice cooperation here between HS, CC, and the UNC system that your state seems to lack. let me float a couple of wacky ideas here and see if anything sounds appealing to you.
does your D have a 33 ACT / 1440 SAT? if so she can get a full scholarship to OleMiss Summer College for High School Students. or if she is short of these, she can get 3/4 or 1/2 scholarship. I just found out about it and we sent in our application materials today. Here is the link:

if your daughter has not had Statistics, she can take it as part of the Pre-Pharmacy summer program. the only other Math class seems to be College Algebra which seems to be below her current level. but she could take Math-ish type programs such as Computer Science or Engineering. there are also three very interesting research project opportunities available.
my S plans to attend both 4-week summer sessions, not because he “needs” to, but because we think it will provide an interesting college campus experience, allow him to take classes not available at CC, break up the CC/HS routine that he is doing, and get him even more excited and focused on going to college. and it is a $4000 program he will be able to attend for free, including room, board, and meal plan. perhaps it is an experience that will energize your D for her Senior year.
another possibility might be West Virginia U’s Early College Program. It costs $50 per credit, and I think out-of-state HS students can take the online classes:

hope this helps.
Some high schools require one to take 3-4 years of math regardless of what level one started at the beginning of HS to fulfill graduation requirements. For instance, if someone entered my HS having completed pre-calculus, they’d still be expected to take an absolute minimum of 3 years of math beyond that level and strongly encouraged to do 4.
Since my public magnet offered advanced math courses well beyond calc I, classmates who ran out of math courses before completing the minimum math requirement did dual-enrollment at local 4-year colleges taking courses mainly geared for advanced undergrad math majors or lower-level grad courses for math department grad students. There was some sort of arrangement to defray the costs, especially considering the majority of students when I attended were low-income to lower-middle class.
Community colleges wouldn’t have been a consideration as none of the ones in my area had any coverage at that level as their main focus was on getting remedial and academically average students ready to transfer to the local 4-year public colleges.
@Wien2NC - Thank you for the links. Yes, she does have the stats for the summer scholarship at Ole Miss. What a fabulous opportunity - love the price!!! She does already have some applications pending for other summer programs, but we will definitely keep this one in mind if the others don’t pan out.
