The exploration follows a clear narrative arc with an unmistakable introduction, theoretical framework, methodology, results and conclusion.
Purposeful organisation is evident via a structured title page, table of contents, numbered subsections, tables and figures.
Arguments and data are presented coherently, making the line of reasoning easy to trace from problem statement to proposed tax model.
Occasional abrupt transitions and a few digressions (e.g., extended Peruvian legal context) slightly disrupt the flow.
Minor formatting issues remain, such as mixed-language figure captions and a truncated section heading under “Ley del.”

B.3Logical structure and clarity

Criteria Feedback
Mathematical notation is used consistently and accurately throughout (variables clearly defined, standard forms y = ax + b properly applied).
A variety of well-chosen representations (tables, software-generated and hand-drawn graphs, algebraic derivations) effectively support the text.
Overall logical structure is clear, with each step of the argument laid out in a coherent sequence.
A small number of minor slips remain (e.g., mismatched parentheses in one equation, inconsistent significant digits in coefficients).
Axis labelling and units on some graphs could be clearer for full precision.
