H1 vs H2 vs IB vs IGCSE Economics: The Four Syllabuses Compared (2026–27)

One reference page for students, parents and private candidates comparing A-Level H1 Economics, A-Level H2 Economics, Cambridge IGCSE Economics and IB Diploma Economics: papers, marks, content coverage, assessment skills, workload, where each one leads in Singapore university admissions, and how to choose.

Assessment facts on this page are checked against the official syllabus documents: SEAB H1 Economics 8843 and SEAB H2 Economics 9570 (2026 examination), the Cambridge IGCSE Economics 0455 syllabus for 2027–2029, and the IB Economics subject briefs for SL and HL (first assessment 2022). Rank-point rules follow the MOE results release of 27 February 2026. Last verified 13 September 2026. Always confirm against the document for the year you are sitting.

Every year the same three groups land on this question from different directions. JC1 students choosing between H1 and H2. International-school students finishing IGCSE and deciding between the IB Diploma, a junior college, or the A-Levels as a private candidate. And parents trying to understand whether an IB 7, an A-Level A and an IGCSE A* mean anything comparable. Most pages answer one pair at a time and the comparisons contradict each other. This page puts all four side by side from the primary documents, states plainly where a figure is our observation rather than a published fact, and links to the deeper guide for each pairing so you do not have to take the summary on trust.

The four syllabuses at a glance

What each syllabus actually is

H1 and H2 Economics: one qualification, two depths

H1 (8843) and H2 (9570) are both Singapore-Cambridge GCE A-Level subjects set by SEAB. They share the same three core themes and the same assessment objectives; H2 adds two content areas, Firms and Decisions and Globalisation and the International Economy, and an essay paper. An H1 subject is designed to take about half the curriculum time of an H2 and carries half the rank points. The full pairwise comparison, including the rank-point arithmetic for dropping from H2 to H1 and the CORE Check decision framework, is in H1 vs H2 Economics: every difference that matters; the complete H2 syllabus walkthrough is in the H2 Economics complete guide.

Cambridge IGCSE Economics (0455): the foundation course

IGCSE Economics is a pre-16 qualification, the international-school equivalent of an O-Level subject. Its six sections run from the basic economic problem through markets, microeconomic decision-makers, government and the macroeconomy, economic development, and international trade. It uses deliberately simpler vocabulary than the post-16 syllabuses: the syllabus speaks of "total demand" rather than aggregate demand, has no AD–AS model, and lists only competitive markets and monopoly under types of markets. From the 2027 examination the assessment changes: Paper 1 grows to 40 questions in one hour, Paper 2 shrinks to 80 marks in two hours, and the weighting of evaluation falls to 10% of the qualification. KS Academia Prep's guide to the 2027 IGCSE Economics changes lists every content addition and removal, and their ultimate IGCSE Economics guide covers the course in full.

IB Diploma Economics: a different system, not a deeper A-Level

IB Economics is one of the six Diploma subjects, taken at Standard Level or Higher Level. Its four units, introduction, microeconomics, macroeconomics and the global economy, are organised around nine key concepts (scarcity, choice, efficiency, equity, economic well-being, sustainability, change, interdependence and intervention), and every candidate submits an internally assessed portfolio of three commentaries on real news articles. HL adds a third paper, the policy paper, and extension content such as the theory of the firm and market structures that SL students never meet. Grades run from 7 to 1 and feed directly into the 45-point Diploma total that NUS, NTU and SMU use for admission. KS Academia Prep explains the course in What is IB Economics? and the coursework in their IB Economics IA guide.

Paper structure, syllabus by syllabus

Two structural facts stand out once the tables sit together. First, H2 is the only one of the four with no multiple-choice, no coursework and no data-response paper at the IB scale: five hours of writing, all of it externally marked. Second, IB is the only one where a fifth to a third of the grade is decided before the exam hall, which changes how the two years are paced. A student who writes well under time pressure but hates coursework will find H2 more comfortable than HL; the reverse student will not.

Content coverage matrix

The matrix below lists the topics that recur across the four syllabuses and shows, for each, whether it is examined in full, examined at reduced depth or under different terminology, examined only at IB Higher Level, or not examined. It is built from the content outlines of the four documents linked at the top of this page. Where a topic appears at reduced depth, the cell says so rather than rounding up.

Assessment skills: what each exam actually rewards

This table explains most of the "which is harder" arguments. IGCSE's evaluation weighting is one-tenth of the qualification, so a well-drilled student can score an A* mostly on knowledge and analysis. At H2, evaluation is the skill that separates grades; a student who knows everything and judges nothing plateaus at a B. IB sits between the two in exam-hall evaluation but adds two demands the A-Levels never make: sustained independent writing over two years, and a mandatory habit of reading economic news and pinning theory to it.

Which is hardest? Content, skill and grading, answered separately

Content volume. H2 and IB HL are the broadest; the difference is direction. H2 goes deep on firms, market structures and the international economy with Singapore application. HL goes wide on development, sustainability and inequality, and adds the theory of the firm as an extension. H1 and IB SL are the narrower post-16 options. IGCSE is the narrowest by design; it is the foundation.

Skill difficulty. The essay is the hardest single form and H2 examines it for 60% of the grade with no scaffolding. IB essays are shorter and part of a mixed diet. IGCSE's part (d) discussions are essays in miniature. The case study is common to H1, H2 and IB Paper 2, and the H1 version is the largest of the three at 40 marks. Coursework is a skill of its own that only IB tests.

Grading difficulty. Unknown, and anyone who quotes you a per-subject grade distribution is guessing. MOE and SEAB do not publish subject-level A-Level distributions; Cambridge publishes grade thresholds but not the proportion of candidates at each grade by centre type; the IB publishes global mean grades that mix every school in the world. What can be said: an IB 7 and an A-Level A are both awarded to a minority of candidates, and an IGCSE A* is awarded to a larger share than either.

Workload and hours

The two heavy options are heavy in different ways. H2's weight is concentrated in writing volume and exam-hall stamina. HL's weight is spread across two years of reading, coursework drafting and three papers. In our experience the students who struggle most are not the ones who chose the "hard" syllabus but the ones who chose the syllabus whose kind of work they dislike.

Grading scales and how universities read them

Three things the scales do not tell you. An IB 7 in HL and a 7 in SL carry the same points in the Diploma total, but universities read subject prerequisites by level. An H1 A is worth exactly half an H2 A in rank points, and is counted only if it raises your score. And an IGCSE A* in Economics counts for nothing at university directly; its value is in admission to the next stage and in the foundation it gives. Run the A-Level side of this through the Rank Point Calculator, which applies the 70-point rebasing rule, and the IB side through KS Academia Prep's IB points calculator.

Where each syllabus leads in Singapore

A-Level candidates: the 70-point University Admission Score

From the 2026 admission exercise, NUS, NTU and SMU assess A-Level applicants on a University Admission Score out of 70: three H2 subjects (up to 20 points each) plus General Paper (up to 10), with a fourth content subject, whether an H1 or a fourth H2 counted at H1 weighting, included only if it improves the score and then rebased to 70. Project Work is pass/fail. H2 Economics therefore earns its full value only as one of your three counting H2s; H1 Economics is a fourth-subject safety net. The worked scenarios are in the H1 vs H2 guide.

IB candidates: the 45-point Diploma

The same three universities admit IB Diploma holders on the Diploma total and subject-level prerequisites, not through the UAS. Economics is rarely a stated prerequisite for any programme; the subject that is typically checked is Mathematics, and the Mathematics Analysis and Approaches versus Applications and Interpretation question matters more for an Economics or Business applicant than the level of Economics taken. KS Academia Prep's guide to IB and Singapore universities sets out the current requirements by university, and their IBDP subject consultation page covers the SL/HL choices that follow from a target course.

IGCSE candidates: the step before the step

IGCSE Economics does not enter university admission at all. Its two roles are admission to the next stage, whether an IB Diploma programme, a junior college (international students apply through MOE's admissions exercises, where IGCSE results are read as the O-Level equivalent) or the A-Levels as a private candidate, and the foundation it gives for the post-16 course. Whether IGCSE Economics is "needed" for H2 or IB Economics is one of the most common questions we hear, and the answer is no: neither post-16 syllabus assumes prior Economics. It helps; it is not required.

Private candidates

The A-Levels are the only one of the three systems with a full private-candidate route in Singapore: SEAB registers private candidates for both 8843 and 9570 and they sit the same papers as school candidates. Cambridge IGCSE can be sat privately through registered centres. The IB Diploma has no equivalent: every candidate must be registered through an IB World School, which is why students who leave an international school mid-way typically move to the A-Levels rather than continue the IB independently. Registration, deadlines and support for SEAB private candidates are in our complete private candidate guide; candidates who need extra time or other accommodations should read about SEAB access arrangements before the April window closes.

Pathways and switching between syllabuses

The pattern across the table: moving down a level or across systems at the same stage is manageable because the core transfers; moving up late is not, because the extension content is precisely what the shorter course omitted. Decide the level early and the system once.

The Pathway Fit Test: three questions before you choose

For the H1-or-H2 decision inside a JC we use the CORE Check, which lives on the H1 vs H2 page. For the wider question of which system and level to sit at all, the same discipline reduces to three questions, asked in this order.

Seven myths, corrected

Glossary

H1 / H2

Levels of Singapore A-Level subjects. An H1 subject takes about half the curriculum time of an H2 and carries half the rank points. Economics is offered at H1 (8843) and H2 (9570).

SL / HL

Standard Level (150 hours) and Higher Level (240 hours), the two levels at which IB Diploma subjects are taken. HL Economics adds a third paper and extension content.

Case study question (CSQ)

A set of part-questions on two to three pages of textual, numerical and graphical data. The only question type in H1; 40% of H2; the format of IB Paper 2 and of IGCSE Paper 2 Section A.

Internal assessment (IA) / portfolio

The IB coursework component: three commentaries on news articles, each analysed through a different key concept, weighted 30% at SL and 20% at HL.

Policy paper

IB HL Paper 3: two 30-mark questions combining calculations and interpretation with a policy recommendation.

Assessment objectives (AOs)

The categories of skill an examining body assesses and weights. SEAB, Cambridge and the IB each publish their own set; the weighting of evaluation is the biggest difference between them.

Levels of response

Marking by band rather than by point: L1–L3 plus evaluation bands for A-Level extended answers; L1–L3 for IGCSE part (d) discussions; markbands for IB essays and commentaries.

University Admission Score (UAS)

The rank-point total local universities use for A-Level applicants. From the 2026 admission exercise it is out of 70: three H2 subjects plus General Paper, with a fourth content subject included only if it improves the score.

Diploma points

The IB total out of 45: six subjects at up to 7 points each plus up to 3 points from Theory of Knowledge and the Extended Essay. Local universities assess IB applicants on this total and on subject prerequisites.

Contrasting subject

The MOE requirement that every A-Level combination includes at least one subject from outside the student's main discipline group; it may be taken at H1 or H2. H2 or H1 Economics is the most common contrasting subject in a science-stream combination.

Guided learning hours

Cambridge's published estimate of teaching time for a syllabus: about 130 hours for IGCSE Economics. The IB publishes recommended hours per unit; SEAB does not publish hours.

Real-world examples (RWE)

The IB requirement that essays and commentaries apply theory to specific, named real-world cases. Cambridge IGCSE does not require them; the A-Levels reward contextual application without mandating named examples.

Where to go next

Each pairing has its own deeper guide. The A-Level pages are on this site; the IGCSE and IB pages are on KS Academia Prep, where the same author teaches those syllabuses.

If you have settled on the A-Levels and want to see how H2 Economics is taught week to week, the H2 Economics tuition programme page describes the class structure and the tutor; for IGCSE or IB Economics, KS Academia Prep's Economics programmes page does the same. If you have chosen H1 or IGCSE on your own, this page is meant to be enough.
