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

Your exploration is clearly structured and easy to follow from the aim through to the conclusion.

You keep the modelling pathway coherent, with each stage leading logically into the next.

Your headings, table of contents, and separation of appendices make the work navigable.

Some transitions between methods feel abrupt, especially when introducing the Maclaurin route.

A few sections include material that could be shortened or streamlined.

The logical flow would be stronger if each major modelling choice were justified more explicitly.

You use mathematical language and notation mostly consistently and your equations are usually presented clearly.

You make strong use of multiple representations, including tables, graphs, linearized plots, and residual plots.

Your communication of the modelling process is generally clear and readable.

A few sign and notation choices are inconsistent, which makes some steps less precise.

Some algebraic transitions, especially in the linearization and Maclaurin sections, need to be written more carefully.

The explanation of graphs would be clearer if the axes, units, and purpose of each representation were stated more explicitly in the text.
