The student's Internal Assessment could be improved in several areas. The work is not divided into sections with proper titles, and the font size is too small. The student does not introduce the topic of modeling properly and does not provide background information or references about such a mathematical approach. While the student's approach to the topic is described, it does not specify any methods or field of mathematics used. The conclusion relates to the aims expressed at the beginning, but does not refer to the results of their research. The use of technology is clearly indicated and explained, and the exploration is clear and understandable throughout. The consequent parts of the work are linked logically, and the graphs, tables, and diagrams are present in appropriate places. All information outside of the syllabus scope is referenced, and all mathematical formulae, equations, and other calculations are centered. However, the pages are not numbered correctly, and unnecessary or repetitive calculations/graphs/descriptions are present.
