计算器规定

Calculators are permitted for this paper. Most of the marks are in extended writing, but where a question gives you data to interpret, for example a table of food waste, contamination or cost figures, the standard JCQ rule still applies: no retrievable information stored in the calculator, including saved formulae, notes or programs. Clear your calculator's memory before the exam and switch on exam mode if it has one.

  • AO1: AO1: knowledge and understanding of the specified content (20%)
  • AO2: AO2: the ability to apply knowledge, understanding and skills in a variety of situations and to analyse problems, issues and situations using appropriate skills (50%)
  • AO3: AO3: the ability to gather, organise and select information, evaluate acquired knowledge and understanding, and present and justify an argument (30%)

计算器程序

Live percentage change calculation

用途: Get the percentage change between a before and after figure, such as food waste tonnage before and after an intervention, without a separate written formula.

使用时机: For questions giving before-and-after figures and asking for a percentage change.

步骤
When a question gives you before-and-after figures, such as food waste tonnage before and after an intervention, key the calculation as one sequence: new figure, minus, old figure, equals, divide, old figure, multiply, 100, equals. This gives you the percentage change directly without needing a separate written formula.

考试提示: Perform this live from the figures printed in the question. No formula, template or prior working may already be stored in the calculator when the exam begins, which is a JCQ rule that applies across all CCEA exams.

Live proportion calculation

用途: Get what proportion of a total a figure represents, such as the share of a population affected by food insecurity.

使用时机: For questions asking what proportion or percentage of a total a given figure represents.

步骤
To find what proportion of a total a figure represents, for example the share of a population affected by food insecurity, key the part, divide, the whole, multiply, 100, equals, as one continuous sequence rather than estimating.

考试提示: This is a live, on-the-spot calculation from data given in the exam. Nothing may be stored in the calculator's memory beforehand, including saved figures or formulae, under CCEA and JCQ rules.

常见错误

  1. 1high涉及分数: 8Food waste and sustainability

    Covering only one side of a two-part essay stem, for example detailing the environmental impacts of food waste while barely mentioning the ethical issues the same question asks for.

    如何避免: Plan both required elements as two labelled sections before you write, and check your word count is roughly balanced between them once you have finished.
  2. 2high涉及分数: 4Food safety and quality

    Writing a Section B essay on chemical or microbiological safety without naming a specific example, such as the mycotoxins patulin or ochratoxin A, or the additives aspartame or MSG.

    如何避免: Learn two or three named examples for each major topic in your option and use their proper names in your essay rather than describing the category alone.
  3. 3medium涉及分数: 2Chemical contamination

    Confusing the regulatory terms Maximum Residue Limit, Acceptable Daily Intake and Tolerable Daily Intake when discussing chemical safety limits.

    如何避免: Fix each term to what it actually limits: MRL is a residue level in a specific food, ADI is a daily intake judged safe over a lifetime, TDI is the equivalent for a contaminant rather than an intentional additive.
  4. 4medium涉及分数: 3Food sustainability

    Giving a superficial, descriptive answer instead of an analytical one, for example stating that monocropping harms the environment without explaining how it causes soil erosion and nutrient depletion.

    如何避免: After every claim, add one sentence explaining the process that causes it, not just the fact that it happens.
  5. 5medium涉及分数: 2Allergens

    Treating food allergy and food intolerance as the same thing, when an allergy is an immune-mediated response and an intolerance is not.

    如何避免: State the mechanism whenever the distinction matters: allergy involves the immune system reacting to a protein, intolerance does not.
  6. 6medium涉及分数: 3Controls and legislation

    Assuming Environmental Health Practitioners only carry out reactive restaurant inspections, missing their broader statutory duties in drinking water surveillance, food sampling and outbreak tracing.

    如何避免: Learn the full range of a named body's statutory duties, not just its most familiar role, before you use it as evidence in an essay.
  7. 7high涉及分数: 4Paper technique

    Treating Section A part (b), worth 15 marks, as a set of brief notes rather than an extended, coherent piece of analysis.

    如何避免: Write Section A part (b) in full paragraphs with the same structure you would use for a Section B essay, since it carries almost as many marks as one.
  8. 8high涉及分数: 4Quality of written communication

    Losing Level 4 marks through poor structure, repetitive points and a lack of precise, subject-specific terminology in the 20-mark essays.

    如何避免: Plan each essay in named paragraphs before you write, and use the correct technical term the first time a concept appears rather than an everyday substitute.
