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

Your exploration is clearly structured with an introduction, modelling sections, comparison, conclusion, and bibliography.

The overall progression is easy to follow because you return consistently to the same research question throughout the work.

Your repeated use of labelled sections, tables, and graphs helps the reader navigate the investigation.

Some figure captions, numbering, and graph presentations are not fully clean or consistent.

There is avoidable repetition in the written explanations and routine calculations.

A few key modelling choices are asserted rather than explained in enough detail, which weakens the flow at points.

You use appropriate mathematical language such as piecewise functions, domains, integrals, scaling, and percentage comparison.

You make strong use of multiple representations, including images, graphs, tables, equations, and numerical summaries.

Your reasoning is generally easy to follow because the mathematical steps are presented in a logical order.

Some notation is inconsistent or malformed, especially in a few of the final area expressions.

A few integrals and percentage comparisons are not written in a completely standard or immediately clear form.

Some coordinate-system and axis choices need to be explained more explicitly so the reader can interpret the models without confusion.
