Additionally there are 10 marks given for organisation andpresentation. You will be expected to show evidence of research andwell balanced arguments supported by academic literature relevantto the problem (in addition to the learning package material). Notethat that the marking scheme gives an indication of the expectedlength of each section. Explanations and descriptions shouldreflect this balance between sections and sub-sections.
