Excellent
Coherence and logical development
Excellent
Organization and structure
Good
Conciseness and relevance
Criteria Feedback
The exploration is highly coherent with a smooth narrative progression through data selection, modelling, numerical schemes and error analysis.
Well-structured with a clear contents page, numbered sections, headings and a concise conclusion facilitating easy navigation.
Several lengthy pharmacological background sections dilute conciseness and could be condensed.
Minor formatting inconsistencies (e.g. dot leaders in the contents page, citation style) slightly detract from polish.
Criteria B: Mathematical Communication

Good
Mathematical language and notation
Good
Multiple representations
Good
Logical structure and clarity
Criteria Feedback
Mostly consistent and accurate use of mathematical language and notation (calculus symbols, subscripts, Taylor series) throughout the text.
Effective use of multiple representations (tables, graphs, algebraic derivations, schematic diagrams) to support understanding.
Logical explanations and step-by-step derivations are generally clear for an HL audience.
A few graphs lack clear axis labels/units and resolution could be improved.
Occasional overuse of math mode in headings and missing uncertainty measures in regression results reduce clarity.
