The student's work is divided into sections, including an introduction, body, and conclusion. The body of the work is further subdivided to clearly indicate different phases of the exploration. The topic of the Internal Assessment, "Modelling the population of Singapore," is stated clearly and explained in the introduction. The student's conclusion provides a summary of the outcomes and responds to the aim stated in the introduction. The exploration is clear and understandable throughout, and the consequent parts of the work are logically linked. The graphs, tables, and diagrams are appropriately placed in the body paragraphs. Large tables are attached as appendices, and the font used is 12pt with double spacing. All mathematical formulae, equations, and other calculations are centered. However, the student should provide references for information outside of the syllabus scope and ensure that the pages are numbered correctly.
