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

Your report has a clear overall flow from the physical setup to the final conclusion.

Sections are well signposted and the reader can follow your mathematical journey easily.

Most of the content stays focused on the research question and supports the investigation.

Some parts repeat the same idea instead of moving the argument forward.

The scope shifts slightly near the conclusion, which weakens the sense of a single tightly controlled investigation.

A few layout choices leave the report less streamlined than it could be.

You use a good range of mathematical language, including vectors, differential equations, logarithms, and numerical methods.

Your diagrams, tables, and graphs help make the model easier to understand.

The mathematical work is usually presented in a readable and visually clear way.

Some symbols are used inconsistently, which makes the notation less reliable.

A few formulas and definitions are not introduced in a fully standard order.

The communication becomes weaker when you switch between similar but not identical meanings for the same variable.
