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

The exploration is very easy to follow because it has a clear roadmap, headings, page numbering, and a strong overall progression from motivation to conclusion.

Your diagrams, model screenshots, and labeled visuals are placed well and help the reader understand the two horn models.

Some sections are much longer than needed, which makes the work less concise than it could be.

A few derivations become hard to track because the algebra is expanded too fully and key transitions are not always signposted clearly.

You use appropriate mathematical language across calculus, geometry, trigonometry, and 3D modeling.

Different representations are used effectively, including symbolic derivations, graphs, diagrams, CAD outputs, and mesh-volume checks.

Your explanations are usually clear enough for the reader to follow the mathematical reasoning.

There are several notation and transcription issues, such as inconsistent symbols and some incorrect trig writing.

Some claims blur the line between an exact mathematical result and a numerical approximation from a CAD mesh.

A few steps would be clearer if you stated the purpose of the method before carrying out the algebra.
