IB Mathematics Applications & Interpretation (AI) HL Internal Assessment Example

The student's exploration is clearly structured and easy to follow, with a strong introduction, logical sectioning, and a coherent overall flow.

Most of the material stays relevant to the enzyme-kinetics investigation, and the student's main line of argument is easy for the reader to track.

The student's headings, tables, and figures help organize the investigation effectively.

Some sections are longer than necessary and include background that does not add much to the mathematical argument.

The claim of an 'optimal' range is not fully justified by a defined mathematical criterion.

A few sections, especially the decay discussion, feel somewhat detached from the central line of development.

The student uses mathematical notation, biochemical symbols, and equations appropriately in most places.

A range of representations is used well, including derivations, tables, and graphs.

The writing is usually clear and the formatting is polished, which supports readability.

Some notation is inconsistent, especially with the use of variables for reaction rate.

A few mathematical statements are not expressed precisely, which reduces clarity.

Some graphs and transformed representations become crowded or are not fully supported by the accompanying interpretation.
