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

The exploration follows a clear logical development, with each section (introduction → proof → checking → extension → conclusion) building sensibly on what precedes it.

Good use of headings, numbered equations and labelled figures provides a recognisable and navigable structure.

Most of the content is directly relevant to the central question, maintaining reader focus on the key arguments.

Several passages are verbose or contain unnecessary repetition, interrupting the flow.

Occasional duplication of images and a few misplaced paragraphs (eg. lengthy coordinate lists) prevent truly seamless organization.

Some tables and figures (eg. the table for n≤10, low‐resolution screenshots) lack clarity or proper labelling, reducing conciseness.

Variables and indices are defined clearly, and the student employs precise mathematical notation throughout most of the exploration.

A broad range of representations (algebraic derivations, labelled diagrams, data tables and GeoGebra graphs) are integrated effectively and interpreted in the text.

Logical structure is strong: premises are stated, equations are numbered and conclusions are drawn explicitly, yielding clear mathematical communication.

There are a few minor notational inconsistencies (eg. switching between R1 and R_1) and missing differentials in derivative expressions.

Occasional mis-numbered equations and abrupt algebraic jumps slightly obscure the chain of reasoning.

Some screenshots and figures could be better labelled to strengthen the link between representation and analysis.
