Ah - this is such a hard one! I have had to work incredibly hard to keep D11 motivated. While she did well in Math, she missed being in the GT classes due to her Eng scores. But she is very happy to settle at the easiest levels. Setting small goals, with just that little bit of challenge has worked best for us. Finding a peer who is similarly inclined, getting involved in Battle of Books, Science Bowl kind of competitions also helped us.
