The student consistently and correctly uses correct mathematical notation, symbols, and terminology. They appropriately use multiple forms of mathematical representation such as formulae, diagrams, tables, charts, graphs, and models. All mathematical calculations are explained and any data presentation is described. The student also labels the graphs, tables, and diagrams at the bottom. However, they should explain the main concepts in the introduction to ensure the reader's understanding of the work. Additionally, the degree of accuracy is not stated for any rounded values, which should be addressed by the student.
