The student has effectively applied a range of qualitative and quantitative source material to explore the distinct marketing strategies of Tesla, including sources from differing origins and types. They have also placed their sources into a wider business context by considering multiple automotive markets based on geography. However, the student needs to improve the referencing of source material in the essay's body to fulfill the subcriterion of effective referencing. Additionally, they should work on explaining technical or subject-specific terms and introducing each tool analysis with a consideration of the definition of each tool to demonstrate their business knowledge. On the positive side, the tone and register of the essay are analytical, academic, and not informal, with the inclusion of correct and necessary terminology without oversaturating the work with subject-specific jargon, enhancing the essay's clarity.
