Hmmm...with AOS section III, it is generally expected that it'll be an essay though there *is* leeway for it to be other mediums. What must be remembered though, is that this paper is held in common by Advanced and Standard, so I am not sure if they would present anything too out there. This would probably be different for many people's internals which may have been designed with an Advanced class in mind. So while it *can* be something other than an essay in section III, I doubt it will be.
