The student has organized their work effectively by dividing it into sections and further subdividing the body to clearly indicate phases of exploration. The topic of the Internal Assessment is stated clearly and explained in the introduction, although the outline of the mathematics used in the exploration is missing. The conclusion provides a summary of outcomes and responds to the aim stated in the introduction. The exploration is clear and understandable throughout, with consequent parts linked logically. Graphs, tables, and diagrams are present in appropriate places, and all information outside the syllabus scope is referenced. However, double spacing is not applied, and unnecessary or repetitive calculations/graphs/descriptions are absent.
