- You use headings and tables effectively so the reader can follow the progression of the work.
- The topic is relevant to your personal interests and gives the project a clear direction.
- Some sections include unnecessary material that distracts from the main question.
- A few parts of the argument do not flow securely because model results are interpreted too confidently.
