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

Your exploration is very clearly structured, with a strong introduction, logically ordered sections, and a conclusion that is easy to follow.

Your visuals, numbering, and appendices make the document professionally presented and help the reader navigate the work.

Most of the content stays focused on the central question and the main mathematical development is easy to track.

Some sections are longer than necessary and repeat general explanation more than they need to.

A few tangential elements reduce conciseness and do not add much mathematical value.

Some conclusions would be stronger if they stayed more tightly within the tested interval and evidence.

You use mathematical notation, terminology, and function language appropriately for most of the exploration.

You include several different representations, such as algebraic derivations, graphs, tables, and error comparisons, which helps communicate the mathematics effectively.

Your explanation is usually logically sequenced, so the reader can follow how each calculation leads to the next stage.

There are a few notation and sign inconsistencies that weaken precision.

Some graphs and tables could be labelled more clearly so the meaning of each value is immediately unambiguous.

At times the explanation becomes verbose, which slightly reduces clarity.
