よくあるミス

1. 1high影響する配点: 2Resource management and sustainable production

   Confusing the waste mitigation strategies of reconditioning and re-engineering.

   回避方法: Remember that reconditioning restores an old product to look and perform as new without major design changes, whereas re-engineering involves redesigning components or workflows to improve or alter the product's performance.
2. 2high影響する配点: 3Sustainability

   Using vague, colloquial terms like 'environmentally friendly' or 'raising awareness' instead of syllabus-defined keywords.

   回避方法: Deploy precise syllabus terms such as 'dematerialization', 'decoupling', 'cradle-to-cradle loop', or 'reducing material throughput'. Vague phrasing is explicitly blocked by markschemes.
3. 3medium影響する配点: 1Innovation and design

   Failing to write a descriptive second sentence in 2-mark 'Outline' command-word questions.

   回避方法: Apply the 'ID + Dev' rule: use your first sentence to clearly state or identify the factor, and your second sentence to explain the mechanism, cause-and-effect relationship, or consequence.
4. 4high影響する配点: 4Modelling

   Writing unbalanced answers for the 9-mark extended response questions in Paper 2 Section B.

   回避方法: Structure your essay into three distinct, balanced parts under clear sub-headings matching the three prompts (e.g., Materials, Pollution, and Energy) to avoid being capped at low mark bands.
5. 5medium影響する配点: 2Commercial production

   Confusing Quality Assurance (QA) with Quality Control (QC).

   回避方法: Define QA as a proactive, process-oriented system focused on designing stable workflows to prevent defects, and QC as a reactive, product-oriented system focused on detecting defects through testing.
6. 6medium影響する配点: 2Raw material to final product

   Confusing physical properties (such as mass and density) with mechanical properties (such as toughness and hardness) during material selection analysis.

   回避方法: Remember physical properties describe the material's basic physical state under no load (density, mass, electrical resistivity), whereas mechanical properties describe how the material behaves under applied physical forces (toughness, hardness, tensile/compressive strength).
