I'm taking notes. We're in the same boat, here -- DS11 will be 15-turning-16 when he starts his senior year, assuming no more skipping. His birthday was six days past the cutoff when we skipped him over kindergarten and into 1st grade, and he just skipped 6th grade, too.

We're just starting to get close to the muddy waters, so I can't tell you how it's likely to pan out.
