Legal studies grade reports for trial exams

I am completing the old VCE Legal studies exams for revision, which are good resource, but I find that when marking them they are genuinely impossible to self-mark despite my teacher encouraging this. With no marking criteria just "possible points you could cover" and the way vcaa describes a correct answer is so shallow and dramatic, like "eloquent or rich" is useless just outline a depth mark. Anyone else encountered the same issue or found a workaround? Good luck to everyone doing legal studies on Monday!
