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

Your report is exceptionally well structured, with a clear title page, contents page, section headings, and a logical flow from context to conclusion.

Most of your figures and calculations are placed close to the relevant discussion, which makes the exploration easy to navigate.

The overall presentation is professional and visually consistent.

A few diagrams, especially some early GeoGebra images, are difficult to interpret because labels are small or transparency reduces clarity.

Some repeated derivations make parts of the report longer than necessary.

The geometry and area setup are not always introduced with enough consistency, which weakens the clarity of later sections.

You use appropriate mathematical language such as vectors, plane equations, cross products, parametric lines, and trigonometric notation.

You include multiple representations, including algebraic work, diagrams, 3D GeoGebra models, and area comparisons.

Your calculations are usually explained in a clear step-by-step order, which makes the method accessible.

Some notation is not fully consistent, especially around angle definitions and the handling of refraction.

Several diagrams are not labelled clearly enough for a reader to verify the construction independently.

The final quantities are not always distinguished cleanly with units, which makes parts of the communication less precise.
