The student consistently and correctly uses correct mathematical notation, symbols, and terminology and only includes computer notation if it is software-generated. Key terms and variables are defined and explained when first introduced. However, some main concepts are not described in the introduction, such as the rate of change for temperature. The student uses multiple forms of mathematical representation appropriately, explains all calculations, and describes any data presentation. The degree of accuracy is stated for any rounded values, which are only rounded at the end of the calculations thread. The student uses a deductive method and sets out logical proofs where appropriate. However, the graphs, tables, and diagrams are not consistently labeled or numbered.
