Excellent
A.2Organization and structure
Excellent
A.3Conciseness and relevance
Good
Criteria Feedback
- Highly coherent logical progression from personal anecdote through definitions, exploration, proof and application
- Exceptional organization via clear introduction, numbered sections/subsections, integrated tables and figures
- Effective use of signposting and appendices allowing the reader to navigate the document effortlessly
- Occasional digressions (lengthy figure captions, photographs) slightly reduce conciseness
- Some tables and figures could benefit from improved labelling (e.g. units, individual sub‐figure captions)

Good
Criteria Feedback
- Consistent and accurate use of mathematical language and notation throughout (e.g. l_k, induction symbols)
- Clear definitions of variables, indices and constants early on
- Effective use of multiple representations (tables of values, photographs) to support algebraic arguments
- Some hand‐drawn diagrams lack scale labels or dimension markers, weakening the link to algebra
- Occasional typographical errors in subscripts and inconsistent notation reduce precision
- Units are not always clarified (e.g. inside logarithms)
