From 2027, O-Level Social Studies is sat as Paper 1 of SEC G3 Combined Humanities, one 1 hour 45 minute paper worth 50 marks and half of the Humanities grade. Section A is a compulsory source-based case study worth 35 marks across five questions. Section B is two compulsory structured-response questions worth 7 and 8 marks. The other half of the grade comes from the elective, which is Geography (K335), History (K336) or a Literature paper (K337 to K340). Both sections are marked by levels, so how an answer is built matters as much as what it knows.

The Social Studies pages are identical in K335 and K336. Our guide to SEC syllabus codes for 2027 lists the other subjects.
| Question | What it tests | Marks |
|---|---|---|
| 1 to 4 | Handling specific sources: inferring, comparing, judging | 25 in total |
| 5 | Using several sources, seeing the issue from a different perspective | 10 |
| 6 | A reasoned explanation or recommendation set in Singapore, with more than one cause or strategy | 7 |
| 7 | Two factors or perspectives, then a judgement or balanced conclusion | 8 |
SEAB fixes only the total of 25 for Questions 1 to 4, so schools split them in different ways.
The three Issues and their inquiry questions
| Issue | Inquiry focus | Content to revise |
|---|---|---|
| 1. Exploring Citizenship and Governance | Working for the good of society: whose responsibility is it? | Roles of government, differing needs, unequal sharing of costs, trade-offs |
| 2. Living in a Diverse Society | Is harmony achievable? | Race, religion, socio-economic status, nationality, responses to diversity |
| 3. Being Part of a Globalised World | How can we respond to globalisation? | Economic, cultural and security impacts and responses |
The case study may be set on an issue not covered in the syllabus content, and the two sections never share an Issue. Revise all three.
Source question types and how to approach each
SEAB does not name question types. Its syllabus lists skills, such as drawing inferences, comparing views, detecting bias and evaluating evidence. Schools turn these into familiar question stems.
Common case study questions, with one approach each
- "What can you infer from Source A?"InferenceSay what the source suggests but does not state, then quote the line that proves it.
- "What is the message of the cartoon?"MessageGive the creator's view in one sentence, then point to the details that show it.
- "Why was this source published?"PurposeName the audience and what the author wants them to think or do.
- "How similar are Sources A and B?"ComparisonCompare views on the same point, find a similarity and a difference, then give a verdict.
- "How reliable is Source C?"Reliability or usefulnessCheck the content against other sources, then ask who made it, when and why.
- "Are you surprised by Source D?"SurpriseCheck its claims against what you know, then whether its view fits who wrote it.
- "How far do the sources support this view?"AssertionGroup the sources for and against, judge how far each can be trusted, then weigh them.
The assertion card is Question 5. At 10 marks it deserves about 20 minutes.
The five-minute source-reading routine
Many Section A marks are lost through misreading. This is a habit to practise, not an SEAB rule.
- Read the questions firstUnderline the key word in each, such as "infer", "surprised" or "how far".
- Name the dilemmaWrite one line in the margin, such as "parking versus green space".
- Read each provenance line slowlyWho made the source, when, for whom and in what form.
- Mark each source for or againstA plus or minus beside every source becomes your Question 5 plan.
- Circle repeated factsFigures that appear in two sources are the quickest way to cross-check.
A practice case study we wrote
The town, people and figures are invented for this post. The case study sits in Issue 1, where the syllabus covers differing needs, unequal sharing of costs and trade-offs.
Background. Rivermont is a fictional town of about 6,000 households. Its council plans to replace half of Lantern Park, an old neighbourhood park, with a multi-storey car park and a covered market. The playground and jogging track would stay.
Source A. From a speech by the Mayor of Rivermont at a town hall meeting.
Every evening, residents circle our streets looking for a parking lot. Our survey of 800 households found that seven in ten want more parking. Elderly residents have told us they need a market they can walk to. Change is never easy, but a council must plan for every resident, not only for those who speak the loudest.
Source B. A letter to the Rivermont Daily from a retired teacher who lives beside Lantern Park and does not own a car.
The council says seven in ten households want more parking. Only 800 of our 6,000 households were asked, and most of them drive. The half of the park being removed holds the old trees where our seniors exercise each morning. Why must residents without cars pay the price for residents with cars? Before the bulldozers arrive, let every household vote.
Three questions with Level 1 and Level 4 answers
SEAB marks Social Studies by levels of response, but the syllabus does not publish the level descriptors. The ladders and mark splits below are our own summary of how schools usually describe the levels.
Question 1: inference (5 marks)
Study Source B. What can you infer about the writer's view of the council's plan? Explain your answer.
| Level 1 answer | Level 4 answer |
|---|---|
| Source B says only 800 of 6,000 households were asked and most of them drive. It also says seniors exercise under the trees. | I can infer that the writer thinks the plan is unfair to residents without cars. He asks why they "must pay the price for residents with cars", showing he believes one group bears the costs while another gains. I can also infer that he distrusts how the decision was made, since he points out that only 800 of 6,000 households were asked. |
| Copies the source. Nothing is inferred. | Two inferences, each proved with a detail from the source. |
The Level 1 answer is accurate, and that is the trap. The question asks what the source suggests, not what it says.
Question 2: comparison (6 marks)
Study Sources A and B. How different are their views about the plan? Explain your answer.
| Level 1 answer | Level 4 answer |
|---|---|
| They are different because Source A is from the mayor and Source B is from a resident. | The sources differ on the plan. Source A supports it because seven in ten households surveyed want more parking. Source B opposes it because residents without cars lose the trees their seniors use. However, both appeal to the elderly. Source A says they need a nearby market, while Source B says they need the trees. Overall they are mostly different, because they disagree on whether the plan is good for the town even while speaking for the same group. |
| Compares who wrote the sources, not what they say. | A difference and a similarity, each backed by both sources, with a verdict. |
Comparing topics instead of views is a common slip. "Both sources talk about the park" scores almost nothing.
Question 3: the surprise question (7 marks)
Study Source B. Are you surprised by what the writer says? Explain your answer.
"Surprise question" is a school term, not an SEAB one. It is an evaluation question in disguise.
- Level 11 to 2Yes or no, with a reason not drawn from the sources
- Level 23 to 4Checks the content against another source or the background
- Level 35 to 6Judges by the writer's identity and purpose
- Level 47Does both, with a clear overall judgement
Illustrative ladder written by TSS. SEAB does not publish Social Studies level descriptors in the K335 syllabus.
A Level 1 answer reads: "I am not surprised because people dislike change." It checks nothing.
| Point | Level 2 answer | Level 4 answer |
|---|---|---|
| Verdict | Not surprised | Not surprised |
| Content check | Source A also says 800 households were surveyed, so Source B is telling the truth. | Source A confirms the 800 households and the background gives 6,000 in total, so his figures are accurate. |
| Who wrote it and why | Not considered | A retired teacher beside the park with no car loses a space he values and gains nothing from parking, so opposition is expected. |
| What it leaves out | Not considered | Writing to rally readers before work starts, he leaves out the market for elderly residents in Source A. |
| Likely level | Level 2, 3 to 4 marks | Level 4, 7 marks |
The Level 2 answer stops after one check. Asking who wrote the source and why lifts it, and wins marks on reliability and purpose questions too.
A structured-response question with a paragraph plan
Our case study was on Issue 1, so this 8-mark question is on Issue 3. It needs two factors and a judgement.
"Individuals should rely mainly on government support to cope with the economic impacts of globalisation." Do you agree? Explain your answer. (8 marks)
Many schools teach PEEL: point, explanation, evidence, link. It is a common technique for keeping each argument complete, not something SEAB requires.
| Part | What it does | Model wording |
|---|---|---|
| Point | States the factor | Government support helps individuals cope when globalisation puts jobs at risk. |
| Explanation | Says how it works | When firms move work overseas, workers can lose jobs suddenly. Funded training lets them retrain without bearing the whole cost. |
| Evidence | Gives a Singapore example | Singapore Citizens aged 25 and above receive an opening SkillsFuture Credit of S$500 for approved courses. |
| Link | Ties back to the question | So government support lowers the cost of adjusting. |
The second paragraph argues the other side the same way: a credit only helps someone who chooses to keep learning.
The judgement is where Level 4 is won. For example: "I disagree. Support lowers the cost of retraining, but it only works when individuals choose to use it. So individual effort matters more, with government support making that effort easier."
How G2 Social Studies differs
G2 students sit K229, K230 or K231 (reference codes 2125 to 2127). Length, sections and marks are the same.
| G3 (K335 to K340) | G2 (K229 to K231) | |
|---|---|---|
| Answer format | Written on paper | Typed into a digital answer booklet |
| Question 5 | The issue from a different perspective | Relates directly to the case study issue |
| Question 6 | Several causes or strategies | A single cause or strategy |
| Question 7 | Two factors plus a judgement | Explain two factors or perspectives |
| Issue 3 content | Economic, cultural and security impacts | Economic impacts only |
G2 students should practise typing answers early. Our guide on how the SEC replaces the O-Level explains how G2 and G3 are chosen.
Common questions
Is SEC Social Studies the same as O-Level Social Studies?
SEAB maps K335 to K340 onto the old codes 2260 to 2265, and the paper keeps the familiar 35 plus 15 mark shape.
Can my child take Social Studies on its own?
No. At G3 it is offered only inside Combined Humanities, paired with Geography, History or Literature.
What is the surprise question in Social Studies?
It is the school name for questions like "Are you surprised by Source D?" Check the claims against other sources, then explain whether the view fits who wrote it and why.
What if the case study topic was never taught?
SEAB says it may not be covered in the syllabus content. The sources hold the information, so source skills earn the marks.
How long should my child spend on each section?
SEAB sets only the total. A common split is five minutes reading, about 65 minutes on the case study and about 30 on the structured-response questions.
Is PEEL required by SEAB?
No. It is a teaching technique. Markers reward clear reasoning and judgement however the paragraph is built.
