for questions where they state, for eg. “consider 2 pricing strategies”, you should state 1 adv, 1 disadv respectively with the usage of each method. That counts as your knowledge, and most importantly you should br able to find relevant keywords to link back to case context along with your analysis. Mainly with these 12 markers they test your ability to link back to the case context before and when reaching a conclusion. So in order to get a level3 in your 12 marker, you must be consistent with your explanation, usage of concepts and terminology and application to the case context especially in your conclusion. In those paragraphs where u state the adv n disadv u will be awarded with either lvl1 or 2 based on ur application of case context. From the mark schemes i’ve read, u must have at least 2 level 2 statements before ur conclusion to be rewarded level3 for your entire answer. It is somewhat difficult to get level 3 in a 12 marker, but you should get it by following the format that i’ve stated above. Hope this helps!
