HKDSE ERS common mistakes
HKDSE ERS · Understand the traps and how to avoid them.
Writing a personal opinion essay in Paper 1 ('Is euthanasia right? I think yes because...') and never engaging the two ethical theories named in the question.
Candidates treat ERS as a general studies or liberal studies paper, relying on gut feeling and everyday moralising. Under exam pressure, personal conviction feels faster to write than reconstructing a theory, and many have memorised slogans ('respect life') rather than the internal logic of a normative framework.
What to do instead
Before writing, underline the assessable verbs and the theories specified. Structure every body paragraph as: state the theory's principle, apply it to the case's specific facts, then state the conclusion the theory forces. Ban first-person evaluative language from body paragraphs; reserve judgement for the final evaluation paragraph, where you must justify which theory gives the stronger account and why the rival fails on this case.
Describing a theory instead of applying it - writing three paragraphs on what utilitarianism is in general, then one sentence saying 'so it would support this' without calculating or weighing consequences.
Textbook revision rewards recall of definitions, so candidates reproduce definitions because it feels safe and earns marks in class tests. Application is harder because it requires identifying the relevant parties, the harms and benefits, and the alternatives in the stimulus, which takes planning time candidates do not budget.
What to do instead
Practise the 'definition → application → verdict' ratio: no more than two sentences of definition, then at least four sentences applying it to named parties and specific consequences in the case. For utilitarianism, list the stakeholders and their expected benefit/harm in a quick table before writing. For deontology, name the maxim being universalised and test it explicitly.
Confusing the descriptive and normative claims of a religious tradition, e.g. writing 'Christianity says abortion is wrong' without distinguishing what scripture, church teaching, and individual believers hold, or presenting one denomination's position as 'the religious view'.
Candidates compress complex traditions into a single slogan during revision, and textbooks often present a simplified 'typical' position. The exam's live controversies (e.g. contraception, same-sex marriage, end-of-life care) cut across denominations, so the simplification collapses under a well-chosen stimulus.
What to do instead
Build a one-page 'position map' per tradition for each syllabus topic: official magisterium/authoritative teaching, the scriptural or natural-law reasoning behind it, internal dissent or minority readings, and the practical implication. In answers, attribute explicitly ('Catholic magisterial teaching holds...', 'some Protestant traditions emphasise...') rather than asserting 'religion says'.
Ignoring the stimulus material entirely and answering a memorised essay question that merely resembles the prompt, so the specific characters, statistics, or dilemma in the source are never mentioned.
Candidates rehearse model essays on common topics and then pattern-match the prompt to a prepared answer. Time pressure makes reproducing a familiar essay feel more efficient than reading and extracting the stimulus, and some believe 'the case is just an example' rather than the object of analysis.
What to do instead
Spend the first five minutes annotating the stimulus: circle the key facts, note the conflicting values, and identify whose interests are at stake. Then write a one-line thesis that names the stimulus's central tension. Every paragraph should contain at least one explicit reference to a detail from the source (a quoted phrase, a named person, a figure).
Presenting only one side of a contested issue and concluding with an unsupported assertion, so the evaluation section reads 'therefore it is wrong' with no engagement with the strongest counter-argument.
Moral conviction plus time pressure produces advocacy rather than analysis; candidates fear that presenting the opposing view will look like they agree with it. Many also mistake 'evaluation' for 'giving my view' rather than weighing arguments against criteria.
What to do instead
Use the steel-man structure: state the strongest version of the opposing position, then rebut it with a specific reason (a logical inconsistency, a factual error, a consequence the opponent cannot accept). Adopt explicit evaluative criteria - consistency, universalisability, respect for persons, consequences - and apply them, rather than asserting a verdict.
Misusing technical vocabulary - calling any rule-based view 'deontology', labelling a religious ethic 'utilitarian' because it seeks good outcomes, or using 'relativism' and 'pluralism' interchangeably.
Key terms look familiar from everyday usage, and candidates learn labels without the defining commitments behind them. Under pressure, the nearest-sounding word is used, and the marker treats a category error as a conceptual failure.
What to do instead
Maintain a glossary with, for each term, a one-line definition, a distinguishing test question, and a canonical example. For deontology: 'Does the act's rightness depend on its consequences? If no, it may be deontological.' For relativism versus pluralism: relativism denies a single true morality, pluralism holds multiple reasonable views coexist within limits. Check every use of a label against the test question before submitting.
Treating 'applied ethics' as current-affairs commentary - citing news headlines, personal anecdotes, or hypotheticals the candidate invents, and never grounding the discussion in the syllabus's ethical frameworks or the given case.
Candidates believe topicality earns credit and that vivid examples show engagement. Because ERS shares content with liberal studies, the habit of illustrating with real events carries over, but in ERS the illustration replaces rather than serves the analysis.
What to do instead
Keep the stimulus as the primary case and use the syllabus framework as the analytical engine. If you introduce an example, use it in one sentence to test a principle ('this would also license X, which the theory cannot accept'), then return to the case. Cut any example that does not advance a step in the argument.
Writing a Paper 2 answer on the wrong elective or answering the required number of questions incorrectly - e.g. answering two questions from the same elective, or attempting more questions than required and leaving the extra ones uncrossed.
Paper 2 requires candidates to choose from elective modules, and the instruction is easy to misread when nervous. Candidates also over-answer to hedge, not realising that markers may not credit extra responses and that time spent on a third answer weakens the two that count.
What to do instead
Before the exam, write the rubric on a card: number of questions, whether electives are mixed, and the instruction on extra answers. In the first two minutes, read all questions, select, and write the question numbers on the answer booklet. Do not start a third answer; instead use remaining time to strengthen evaluation in the chosen answers.
Neglecting the 'personal response' or 'reflection' requirement - either omitting it, or offering a bare assertion ('I have learnt to respect others') with no reasoning or link to the studied content.
Some candidates think reflection is not 'real' philosophy and skip it, while others treat it as a formality and write platitudes. The skill of articulating a reasoned, defensible personal stance is rarely practised in timed conditions, so it is left to the last five minutes.
What to do instead
Prepare a reflection template: what position I held before, what argument or evidence from the course challenged it, what position I now hold, and what remains unresolved and why. Rehearse it on three syllabus issues. In the exam, allocate a fixed block of time for the reflection and ensure it names a specific theory, text, or case rather than generic values.
Mismanaging time and answer structure - spending 25 minutes on a short-answer question and then writing a rushed, planless essay, or producing unparagraphed blocks with no topic sentences and no conclusion.
Candidates write in the order questions appear and give disproportionate time to the first question. Without paragraph planning, ideas are generated as they write, producing repetition and a missing conclusion; many have never practised under full timed conditions.
What to do instead
Do a timed mock with a written time budget (minutes per mark) and stick to it, moving on when the budget expires. For essays, spend three minutes on a skeleton plan of topic sentences before writing, and reserve two minutes to write a conclusion that answers the question directly. Practise writing under a visible clock until the budget becomes automatic.
