JC Subject Combinations | H1, H2, H3, Project Work and University Admission Score

JC Subject Combinations, H1/H2/H3 and University Admission Score

Policy status · 26 September 2026. against current MOE pre-university subject guidance and announced admissions reforms. Individual JC combinations and university prerequisites can change by institution and intake year, so use the receiving school or university as the final authority.

Junior College subject selection is not simply ‘science versus arts’. Students combine subjects at different levels of depth, subject to school offerings, assumed knowledge, prerequisites and workload. The combination also sits inside a rebalanced A-Level and university-admission system.

The usual combination

MOE guidance describes a normal combination of three H2 content-based subjects and one H1 content-based subject, with at least one contrasting subject. Students also take General Paper, Mother Tongue where applicable and Project Work according to current curriculum rules.

What H1, H2 and H3 mean

  • H1 provides breadth and foundational depth in a subject.
  • H2 is the main advanced content level for the A-Level curriculum.
  • H3 is additional specialisation for students with strong ability and interest and may involve advanced content, research or university-linked study.

Prerequisites matter

Some subjects assume corresponding secondary-school knowledge; others have school or centrally set selection criteria. A combination that is theoretically possible nationally may not be offered by every JC.

The A-Level score is being rebalanced

MOE’s current reform direction includes Project Work graded Pass/Fail and a University Admission Score in which the fourth content-based subject is included only if it improves the score. This reduces the incentive to treat every subject as an equal points-maximisation exercise.

Choose for the next learning problem

  1. Check university-course prerequisites for fields the student is seriously considering.
  2. Check each JC’s actual subject-combination menu.
  3. Assess whether the student wants breadth, depth or a specialised path.
  4. Consider the interaction between mathematics/science prerequisites and humanities interests.
  5. Do not choose a fourth subject only for perceived prestige if it damages the whole learning system.

Subject combination is a curriculum design decision

The strongest JC combination is not the one with the largest number of difficult subjects. It is the combination that preserves required future options while giving the student a sustainable two-year learning system. Subject depth, assumed knowledge, school offerings, contrasting-discipline requirements and university prerequisites all matter.

The normal pre-university structure

MOE’s pre-university subject guidance describes the normal combination as three H2 content-based subjects and one H1 content-based subject, with at least one H1 or H2 subject from a contrasting discipline. General Paper is compulsory; Mother Tongue applies where required; Project Work is part of the curriculum under the current assessment framework. Schools may offer additional or alternative combinations within national rules and their own capacity.

LevelFunctionDecision question
H1breadth with foundational depthDoes the student need this subject for breadth or a lighter content load?
H2main advanced content levelIs this a core strength or prerequisite for likely future study?
H3additional specialisation through advanced content/research/university-linked workDoes the student have real capacity and interest after H2 foundations are secure?

Prerequisites fall into different categories

MOE’s pre-U notes distinguish subjects that assume corresponding secondary-school knowledge, subjects with specific prerequisites, and subjects that require school or MOE Language Centre selection criteria. This means “my JC offers the subject” and “I am eligible and prepared to take it” are not the same statement.

The contrasting-subject rule protects breadth

Students are expected to keep at least one subject from a contrasting discipline. A Science-heavy student therefore retains a Humanities/Arts perspective, while a Humanities-heavy student retains Mathematics/Science exposure. The rule prevents specialisation from becoming intellectual isolation too early.

The A-Level assessment system has been rebalanced

  • Project Work: graded Pass/Fail under the rebalanced framework.
  • University Admission Score: the fourth content-based subject is included only if doing so improves the UAS.
  • General Paper: remains a core knowledge/communication component of the JC curriculum.

The policy direction is important: it reduces the incentive to treat every curriculum choice as a points-maximisation contest and gives students more space for broader development.

JC admission itself changes from 2028

For the 2028 admission exercise, MOE is shifting JC admission from L1R5 to L1R4, reducing the counted subjects from six to five. The new JC qualifying threshold is L1R4 16, while the subject requirements continue to preserve representation from Humanities and Mathematics/Science. This admission rule is separate from the later A-Level UAS, but both reforms reduce pressure to load subjects simply for scoring volume.

A subject-combination decision matrix

QuestionWhy it matters
What university fields remain plausible?some courses require or strongly prefer specific subjects
Which secondary subjects are genuinely strong?H2 assumes substantial pace and independent learning
What does this JC actually offer?combinations differ by institution
Is there assumed knowledge or selection?some subjects cannot simply be added after admission
What is the total workload?four content subjects + GP/PW/MTL/CCA is a system, not separate silos
Would H3 add real depth?H3 is useful when it extends mastery, not when it becomes a prestige burden

Do not reverse-engineer university admissions too narrowly at age 16

Prerequisites matter, but a teenager’s interests can still develop substantially. Preserve credible future options without building an unnecessarily punishing curriculum for a profession the student is not actually committed to. The decision should balance optionality and sustainability.

H3 is depth, not hierarchy

H3 opportunities can include advanced content, research projects, papers and university-conducted programmes. A student should take H3 because they have secure foundations and want additional depth—not because “H3” sounds more prestigious than “H2”. The useful test is whether the extra work deepens intellectual capability without destabilising the core programme.

From school combination to civilisation specialisation

JC subject combinations are an early specialisation mechanism. A civilisation needs scientists, engineers, economists, historians, artists, linguists and people capable of crossing between domains. The contrasting-subject rule and flexible depth levels are therefore not administrative clutter; they are one way the education system balances breadth with emerging expertise.

Take one question further

The same learning habit can travel across subjects, while each subject keeps its own methods. These routes help you notice a difficulty, understand one part of it, and return to something you can do.

A word is familiar, but using it is difficult.

Move from recognising a word to retrieving it in a new context. Understand vocabulary plateaus.

Try it without the guide: Choose one word you already know. Close the guide and use it in a new sentence. Explain why it fits; try another context tomorrow.

A piece of writing has ideas, but the reader loses the thread.

Make the order of events and the links between sentences clear. Explore composition writing.

Try it without the guide: Choose one short paragraph. Read the relevant explanation, close it, and revise the paragraph. Ask someone to tell you what happened and why.

The Mathematics seems familiar, but marks still disappear.

Find the first point where the working stops being reliable. Find Secondary 4 A-Math mark leakage.

Try it without the guide: For a Secondary 4 A-Math question you have attempted, locate the first uncertain line. Repair that step, then try a comparable question without the worked answer.

A Science fact is remembered, but the explanation is incomplete.

Connect the evidence to a scientific idea and the resulting change. Follow the Primary Science learning route.

Try it without the guide: Choose a familiar Primary Science example. Explain the evidence, the idea and the result without notes. Then change one condition and explain your prediction.

Two accounts of the world seem to disagree.

Check the question, source, date and evidence before combining claims. Explore the World Knowledge research library.

Try it without the guide: Take one claim. Find the source best placed to support it, note its date, and state what remains uncertain. Return to your original question.

There is plenty of help, but independence is hard to see.

Check what the learner can understand and do after support is removed. Understand how education works.

Try it without the guide: Choose one small task the child has practised. Agree on a calm, brief attempt without prompts. Use what happens to choose one next step, then stop.
