To structure an OTHM assignment for maximum marks, follow a formal report format. This includes: a cover page, table of contents, introduction, detailed body paragraphs mapping directly to learning outcomes, critical analysis, conclusion, and a Harvard-style reference list. But before this, make sure that you read the assessment brief twice to understand what is required and how the work will be assessed. Also, incorporate graphs, tables, and diagrams into the text to support your analysis. It is also recommended to connect with OTHM assignment experts to get their feedback on your content for clarity. And do not forget to proofread the final draft before the submission.
