IB Mathematics Analysis and Approaches (AA) SL Internal Assessment Example

The report is exceptionally coherent and logically developed, with each section flowing naturally into the next.

Headings, sub-headings and page breaks create a clear macro-structure that guides the reader.

Nearly all material is directly relevant, keeping the narrative focused on modeling kettle cooling.

Occasional verbosity and minor digressions (family anecdotes) slightly reduce conciseness.

Figure captions are sometimes too minimal and appendix tables are awkwardly split.

Some repeated algebraic steps could be tightened.

Mathematical terminology and notation are used consistently and accurately throughout.

A broad range of representations (tables, scatter plots, fitted curves, linearised plots, error-analysis tables) are used effectively.

Arguments follow a clear logical sequence, with symbolic work always accompanied by prose explanation.

A few graphs lack full legends or scale labels, which could hinder immediate interpretation.

Minor slips (e.g. omitting the variable in one model instance) appear but do not affect overall clarity.

Some column headings in tables are cramped and missing unit labels.
