One of the things that Portia highlighted above is one of the most important aspects (to me) of the AoPS classes - learning to show one's work. This was driven home by the one hand marked challenge question.
This is where my DD finally learned to show her work instead of just doing everything in her head. Additionally, she also learned some LaTeX formatting tags which made her written solutions look 'professional' which in turn incentivised her to put together a cogent argument supporting her solution. The result of all this is that DD automatically shows her work now in a clear and concise manner.
