HKDSE CSD common mistakes

HKDSE CSD · Understand the traps and how to avoid them.

Mistake 1

Writing a one-sided answer that lists only arguments supporting one position on a policy issue, then concluding that position is correct.

Candidates treat the paper as a values test where the 'right' stance earns marks, and they run out of time to develop counter-arguments, so they stop after the first batch of points.

What to do instead

Before writing, spend two minutes drawing a two-column table of arguments for and against, then structure the essay as thesis, antithesis, and a reasoned judgement. Reserve at least one paragraph for the strongest opposing view and state explicitly why you weigh your conclusion higher.

Mistake 2

Describing a concept such as 'sustainable development' or 'rule of law' in general terms without applying it to the specific case or data given in the question.

Candidates memorise definitions and reproduce them because that feels safe, and they do not check whether the question asks for application rather than recall.

What to do instead

Underline the command word and the case name in the prompt. After each definition, write one sentence beginning 'In this case...' that connects the concept to a named fact from the source or from your own knowledge. If a paragraph has no case-specific noun, rewrite it.

Mistake 3

Ignoring or misreading the data in the source materials, quoting a figure without its unit, year, or base, or drawing a trend claim the data does not support.

Under time pressure candidates skim tables and graphs, or they lift a number into the essay to look evidence-based without checking what it measures.

What to do instead

Annotate each source before writing: circle the unit, the year, and the comparison base. When citing, use the full form ('rose from 12% in 2015 to 19% in 2020') and add one sentence on what the figure does and does not prove.

Mistake 4

Treating 'Citizenship and Social Development' as a current-affairs trivia quiz and filling answers with unconnected news events, names, and dates that do not answer the question.

Candidates believe more examples means more marks, so they dump everything they remember instead of selecting evidence relevant to the issue.

What to do instead

Limit yourself to two or three examples per essay and, for each, state the link explicitly: what the example shows about the issue in the question. Cut any example that cannot be tied back to the command word in one sentence.

Mistake 5

Producing a conclusion that merely restates the introduction, or that introduces a brand-new argument in the final paragraph.

Candidates run short of time and treat the conclusion as a summary obligation rather than the place where judgement is demonstrated.

What to do instead

Draft the conclusion first in note form: state your overall judgement, the criterion you used to weigh the arguments, and any condition under which your judgement would change. Then write the body to support it, and keep new evidence out of the final paragraph.

Mistake 6

Confusing the roles of different parties in a discussion, for example attributing a government responsibility to NGOs, or mixing up the HKSAR Government, the Central Government, and international bodies.

Candidates learn institutions as a list of names without mapping which body holds which power or duty, so the labels blur under exam pressure.

What to do instead

Build a one-page role map for each topic studied: actor, legal basis, main function, and one concrete example of action. Before the exam, self-test by covering the function column and recalling it from the actor name.

Mistake 7

Writing vague evaluative adjectives such as 'very important', 'huge impact', or 'serious problem' without specifying the mechanism, scale, or affected group.

These phrases feel like analysis and are quick to write, so they survive into the final draft where precise reasoning should be.

What to do instead

Apply a substitution test: replace every evaluative adjective with a mechanism ('because it raises rents for low-income tenants') or a measure ('affecting about one in five households'). If you cannot, delete the sentence.

Mistake 8

Losing marks on the extended-response structure by writing one continuous block with no paragraph topic sentences and no visible signposting of argument.

Candidates plan content but not organisation, and handwriting constraints discourage revision once drafting starts.

What to do instead

Use a fixed skeleton: introduction with stance, three body paragraphs each opening with a claim sentence, and a conclusion with judgement. Leave a line between paragraphs and check that reading only the first sentence of each paragraph still conveys your argument.

Mistake 9

Misallocating time so that the final extended-response question is answered in a rushed paragraph or left partly blank.

Candidates spend too long on earlier short items, often rewriting definitions at length, and do not track elapsed time against marks available.

What to do instead

At the start, write the finish time for each section next to its mark allocation and allocate roughly one minute per mark. Practise full papers with a visible clock so the pacing habit is trained before the exam.

Mistake 10

Presenting personal opinion as established fact, or asserting a contested claim without acknowledging that it is contested.

Candidates want to sound decisive and worry that hedging weakens the answer, so they overstate and lose credit for reasoning quality.

What to do instead

Use calibrated language: 'the evidence suggests', 'this is disputed because', 'on balance I judge'. Where a claim is contested, name the opposing view in the same sentence and explain the basis on which you prefer one side.
