you could find out your other rights (like partial homeschooling).
Unfortunately, you have to be prepared that this road might be closed at any time. My friend had her son partially home schooled last year, and was going to do this this year, but this option is no longer available - either you are a full-time homeschooler, or you are a full-time student. She was told that this has something to do with funding.
As for the differentiation within GT classes - our district runs self-contained GT program in 2-5 grades. When kids start at 2 grade, their math is 3 grade math, and there in no differentiation at that level. If you finish your work earlier, you may read a book, that is it.
Reading is better, they have separate reading groups according to their DRA level.
