We haven't been in exactly the same position but have experience of trying to find a pathway that let's our DD13 work at the "right" level in math. She has been accelerated in math. We don't sequence math the way it is in the US but she is working at a year 11 advanced level while sitting in a year 10 class and nominally being a year 9 student. It is essentially a timetabling issue that means she can't be in the year 11 class so she has an external tutor for that material. She is good at maths but I am not sure it is her passion. She can teach herself math but finds that becomes dry and boring as it is simply moving through material. DD comes alive when she is being taught by a subject expert that she can engage with, debate with and question. She gets that from her tutor and that is the only thing keeping her going.

Because of timetabling clashes our DD spends between one and two periods a day in the library working alone, or with one other student, catching up on material they miss going by going to their math class. It isn't that much fun.

I guess I would just be aware that being able to learn the material alone doesnt necessarily have the same impact as having the guidance of a genuine expert who can feed the flame of learning. But I know we don't always get that choice and we have to do the best with what we have. DD hates math at school as it doesn't move at the pace and level she needs despite acceleration. That alone is not enough for her. The tutor has been essential but I think she craves being with other like minds who she can learn with and from.

Is there any option to partial home school and utilize other means of learning such as online classes, college classes, a mentor or tutor? Is there a passionate teacher who might be prepared to work with her? Has the school offered any options of their own if they are reluctant to go with your plan?
