DD's current plan is to become a veterinarian. So yes, there'll be college, but it may be some number of years early (just depending on where she's at academically and emotionally).

We feel like on the upper end we have a lot of flexibility. If she's not ready for full-time college when she runs out of highschool material, she can go abroad a year, study part time, do community college, do a deeper independent study with a tutor, spend a year of volunteering or in an internship (in her areas of interest).

And to agree with Portia about community classes, they may not be intellectually stimulating enough. Though I have to say some of her teachers are absolutely top notch, PhDs with young kids who wanted to keep a hand in their field, or with professional experience in the area (writing, art, etc.).
