Ann: Half Yearly Results Presentation, page-3

I'm a little bit unimpressed/confused by the results. The market seemed to love the results so I think I'm probably on the wrong track here...and I would appreciate the views of those more intelligent than myself.

Sales increased by more than 50%, and yet the revenue paid out to education providers more than doubled, meaning revenue only increased by 27% year over year. Does anyone know why this is the case? It seems like it's the reverse of operating leverage.

Is the revenue paid out to education providers associated with the "Platform SAAS" or the "Services/Marketplace" revenue categories, or both?
