I would be reluctant to pull someone off a higher level track because of junior high grades. I struggled a lot at that age but I think getting yanked from the classes would have made me feel even worse. Organizational skills and confidence were probably my biggest struggle. I was alllll over the place emotionally, too, it was not pretty.
When it clicked it clicked and I was fine. And then I decided on my own to focus on AG math and not English, but in a way that framed it as what my interests were, not as a failure.
If she wants to drop down I would let her. If not I would try to find a way to make it work.
But my oldest kid is 6, so take my advice with a grain of salt
