The student's work for the criterion of structure is well-organized, with clear subdivisions in the body of the work and a clear statement of the topic in the introduction. However, the conclusion lacks a summary of the results of the SIR model application to the Ontario population. The use of technology was not relevant to this exploration, and the graphs, tables, and diagrams are appropriately placed and follow a logical order. The work is 12-20 pages long, and all information outside of the syllabus scope is referenced. All mathematical formulae, equations, and other calculations are centered and the pages are numbered in the bottom right corner. There are no unnecessary or repetitive calculations, graphs, or descriptions.
