A child who receives PSLE Score 23 or 24 with Standard Mathematics and Science both at AL5 or better ordinarily applies to secondary schools through Posting Group 2. Under Full Subject-Based Banding, the child may be eligible to study G3 Mathematics and G3 Science while English and Mother Tongue ordinarily begin at G2 unless a separate subject-level option applies. Parents should compare the actual school admission range for PG2, confirm the receiving school’s individual subject offers and examine how the child reasons about equations, interprets scientific evidence, understands written instructions and manages the school week. Two strong STEM grades are not a way to obtain a PG3 school place when the overall score is 23 or 24.

For the 2026 PSLE cohort entering Secondary 1 in 2027, currently published school score ranges reflect the 2025 PSLE cohort admitted in 2026 and must not be presented as guaranteed future cut-offs. Punggol Secondary and Kranji had historical non-affiliated PG2 cut-offs of 24; Greenridge, Queensway and Bedok Green recorded 25; Edgefield and Riverside recorded 23. At score 24, those figures represent an earlier boundary, a one-point numerical margin or a historical reach respectively. Parents should select six genuinely acceptable schools after checking current subjects, school programmes, support in English and Mother Tongue, daily transport and the child’s own interests.

Quick parent summary
• PSLE Score 23–24: ordinarily Posting Group 2 for the Secondary 1 school choice.
• Standard Mathematics AL5 or better and Standard Science AL5 or better: each meets the published criterion for possible G3 study from the usual G2 starting level, subject to actual school offers.
• Two G3 subjects do not change a score-23 or score-24 child into a PG3 school applicant.
• English and Mother Tongue usually begin at G2; the child may need additional literacy or language support depending on individual grades.
• Compare only the school’s historical 2025 PG2 cut-off for 2026 entry; it is not a 2027 guarantee.
• At score 24, a previous PG2 cut-off of 23 is a reach, 24 a boundary and 25 a one-point historical margin.
• Rank six genuine school preferences based on teaching, STEM opportunities, CCA, wellbeing and a workable commute.

Definition lock: PG2 admission and G3 STEM subjects are different

The PSLE total adds four Achievement Levels, with a lower number indicating stronger overall examination achievement. At scores 23 and 24, the current ordinary S1 posting route is Posting Group 2. The family cannot choose PG3 simply because the child did particularly well in Mathematics or Science; the PG2-or-PG3 option exists for aggregate scores 21 and 22.

Under Full Subject-Based Banding, individual subjects may be learned at more demanding levels when the pupil is eligible. A child whose indicative starting level is G2 and who attained Standard AL5 or better in Mathematics or Science may be offered that subject at G3. The receiving school confirms actual offers, timetable arrangements and any deadline for responding.

A pupil might have Mathematics AL5, Science AL5, English AL6 and Mother Tongue AL7, giving total 23. Another might have Mathematics AL4, Science AL5, English AL7 and Mother Tongue AL8, giving total 24. Both satisfy the stated subject-grade threshold for Maths and Science. Their needs in the other subjects are different, and the family should investigate that difference before choosing a school.

The child should understand the distinction. PG2 is a school admission route and generally guides the initial level of most subjects; G3 Mathematics and G3 Science are two potential subject classes. The pupil can be proud of STEM achievements without treating other subject levels as a personal failure or believing the combination guarantees future examination results.

What the PG2 timetable may actually mean

Subject or school experience	Usual PG2 start	Potential option or consideration
Mathematics	G2	G3 if Standard AL5+ and school offers
Science	G2	G3 if Standard AL5+ and school offers
English Language	G2	Separate G3 eligibility only if its own Standard AL qualifies
Mother Tongue Language	G2	Different level or school-specific language arrangements under applicable criteria
Form class and common subjects	Mixed form class with pupils of different strengths	Subject lessons can be organised by learning level
CCA and applied learning	Schoolwide student opportunities	Check actual participation and selection requirements

A pupil studying G3 Mathematics and Science may need to handle more complex equations, graphs, scientific vocabulary and practical investigations. The child also has English and Mother Tongue homework, common-curriculum subjects and CCA commitments. The overall load must be assessed honestly rather than assumed to be suitable merely because two PSLE grades met the threshold.

Ask the receiving school how pupils are assigned to learning groups, when the child should respond to an offer and what happens if a higher-level subject becomes difficult. Some schools issue notices through Parents Gateway; actual dates and procedures belong to the current school, not to a general guide written before the posting result.

Mixed form classes allow students with different subject strengths to participate in common activities. This can support social connections and a wider understanding of learning. Parents should avoid describing pupils at G2 as weaker people than peers at G3. The appropriate subject level is a teaching decision, not a human ranking.

A strong education plan includes independence and belonging. The child should learn how to organise homework, seek help when confused, understand lab safety and participate in an activity they enjoy. These habits matter just as much as the formal subject levels.

2025 historical PG2 school examples for parents

The following examples are non-affiliated last-posted PG2 scores for the 2025 PSLE cohort entering Secondary 1 in 2026. They are historical, not the 2027 cut-offs. Check the current school details and any affiliation in MOE SchoolFinder. The table is not a national recommendation to travel far from home.

Secondary school	2025 PG2 COP	Area and practical school-fit question
Edgefield Secondary School	23	Punggol; actual Maths and Science subject offers
Riverside Secondary School	23	Woodlands; Full SBB and pupil support
Dunman Secondary School	23	Tampines; Science teaching and school culture
Kranji Secondary School	24	Choa Chu Kang; sustainable design and leadership
Punggol Secondary School	24	Punggol; local journey and applied learning
North Vista Secondary School	24	Sengkang; student life, teaching and support
Hougang Secondary School	24	Hougang; school environment and curriculum
Greenridge Secondary School	25	Bukit Panjang; projects and Mathematics support
Queensway Secondary School	25	Queenstown; Maths, Science and student wellbeing
Northbrooks Secondary School	25	Yishun; subject-level timetable and school activities
Bedok Green Secondary School	25	Bedok; accessible east-side opportunities

For a pupil scoring 24, a school whose previous PG2 cut-off was 23 is a historical reach, a school ending at 24 is the old boundary, and one ending at 25 gives a one-point numerical margin. At score 23, a previous endpoint of 23 is the boundary, 24 gives one point and 25 gives two. None of these is a personalised admission probability or a promise.

The school score range records the first and last pupil posted into the group in a completed exercise. The actual cut-off next year depends on the cohort’s results, choices and vacancies. A pupil matching the old cut-off may face tie-breakers at a school’s final available place. Parents should use school data to build a balanced list rather than speculate that one point guarantees success.

Do not read a school’s PG3 score when planning a PG2 application. Kranji’s prior PG3 cut-off was 14 whereas its PG2 cut-off was 24. The latter is the relevant historical number for a score-23 or score-24 pupil entering PG2, even if the pupil later studies two subjects at G3.

A school with a historical cut-off of 23 is not automatically better at Science or Mathematics than one ending at 25. Cut-offs reflect past applications and cannot measure laboratory teaching, the effectiveness of feedback, school culture or whether a particular child feels confident there. Those need to be investigated separately.

Mathematics readiness: more than fast arithmetic

PSLE Mathematics AL5 or better can indicate a good foundation, but the secondary curriculum introduces greater abstraction. Pupils work with negative numbers, algebraic expressions, equations, ratio and more formal geometric reasoning. A child who has memorised arithmetic procedures may find unfamiliar symbolic tasks challenging.

Ask whether the pupil can explain why a method works. If a quantity is multiplied by three and increased by five to make twenty, can the child represent that relationship as 3x + 5 = 20 and explain the meaning of x? Can they preserve equality by applying the same operation to both sides? Checking the solution through substitution is a useful habit.

The family should pay attention to fractions and proportional reasoning, because gaps in these topics often reappear inside algebra and Science calculations. A pupil may know how to multiply fractions by procedure yet not understand what the resulting quantity represents. Diagrams and number lines can help expose and repair the misunderstanding.

G3 Mathematics should develop accurate, flexible reasoning rather than simply more questions. A school that can classify errors—reading, concept, arithmetic, notation or working presentation—may provide more effective support than one that treats every wrong answer as carelessness.

The transition into algebra: a parent-friendly example

A useful way to explain algebra is to begin with a familiar relationship. Three equal bags contain eighteen marbles altogether. A Primary 6 pupil may calculate eighteen divided by three. In Secondary 1, the same relationship can be written as 3x = 18, where x represents the marbles in one bag. The equation expresses balance.

Now change the condition: the three bags and two loose marbles total twenty. The relationship becomes 3x + 2 = 20. The child must understand the role of the extra two before solving for x. A memorised instruction such as ‘move the two across’ is fragile if the pupil cannot explain what operation preserves the equality.

Ask the child to check the answer by substitution. Does the value of x make the original relationship true? This habit helps pupils notice arithmetic and notation mistakes. When fractions or negatives are introduced, the same balance principle continues to apply.

Parents do not need to finish an entire algebra chapter during the school holiday. The objective is to connect meaning, representation and reasoning so that the pupil can approach new Secondary 1 lessons with confidence and questions rather than a dependence on shortcuts.

Science readiness: understanding evidence, not merely keywords

A strong PSLE Science grade does not necessarily mean every kind of scientific explanation is secure. Some pupils recall facts accurately but struggle to apply them to unfamiliar investigations. Others enjoy demonstrations and diagrams but find it difficult to form a precise written conclusion.

Secondary 1 Science places importance on identifying variables, recording observations, reading graphs and explaining the relationship between evidence and scientific ideas. A student who says ‘the plant grew faster because it got more water’ should consider whether other conditions were also different before making a confident causal claim.

Ask what was measured and what could affect the result. If two experiments use different quantities and temperatures, can the pupil decide which condition explains the difference? Fair-test reasoning requires careful control and honest interpretation. These skills should be practised through safe observations and school materials rather than hazardous home experiments.

G3 Science may also demand a more formal explanation structure. A child can learn to state a claim, identify evidence and explain why the evidence supports it. Scientific writing should be precise and conceptually accurate, not simply full of long words copied from model answers.

Data, graphs and rates: where Maths and Science meet

Mathematics and Science share skills in measurement, numerical comparisons, graphs and rates. A pupil who understands ratio may find it easier to analyse a scientific data table, while an interest in experiments can make mathematical concepts more meaningful. This is an opportunity for connected learning across the two strong subjects.

However, a correct calculation cannot substitute for the right scientific conclusion. A child might calculate that temperature rose by six degrees but misunderstand what caused the change or whether the comparison was fair. Parents should ask both what the numbers mean and what the experiment actually supports.

Graph-reading is a useful bridge. Ask which quantity is on each axis, what unit is used and whether the graph shows an increase, decrease or stable value. Then discuss whether the relationship is sufficient to conclude cause and effect. This develops quantitative reasoning and scientific caution together.

A school with practical STEM activities may encourage these connections. Ask whether ordinary pupils collect and interpret evidence, whether project conclusions are reviewed and whether teaching extends beyond memorising competition answers. The point is to build transferable skills rather than a collection of advanced-looking projects.

The hidden risk: strong STEM results can conceal English needs

A child with Maths AL4, Science AL5, English AL7 and Mother Tongue AL8 has PSLE total 24. Their strengths in numerical and scientific thinking are genuine, yet English reading and written explanation may need targeted support. Scientific questions often require detailed interpretation of instructions and precise use of language.

Ask the Primary 6 teacher whether the pupil struggles with vocabulary, sentence meaning, reading stamina or organising written responses. A student may understand an experiment when the teacher explains it aloud but fail to interpret the written question independently. That can affect the child’s performance in both English and Science even when the scientific concept is known.

A PG2 starting route ordinarily begins English at G2. Parents should investigate how a school teaches reading strategies, inference and clear writing. A short daily reading routine based on the child’s interests can be helpful, but the school should address specific skill gaps rather than simply assign more difficult passages.

Strong Mathematics cannot remove the need for literacy, and strong Science does not automatically create an elegant written explanation. A school that recognises and supports this uneven profile may be more suitable than one chosen solely for a historic reputation for STEM.

Mother Tongue support: a separate learning challenge

Mother Tongue may be less secure for a child who is strong in Maths and Science. The exact language—Chinese, Malay or Tamil—matters because the writing system, vocabulary and teaching arrangements differ. Some pupils converse comfortably but struggle with formal reading or composition. Others recognise written words but hesitate in spoken discussion.

Ask the teacher which component is causing difficulty. Is the pupil unsure of characters or script, unfamiliar with sentence patterns, lacking vocabulary or slow at reading longer texts? A reliable intervention focuses on the first unstable skill rather than expecting a child to memorise an entire list of difficult expressions without understanding.

Under Full SBB, certain students who face significant difficulty with Mother Tongue may be eligible to study it at a less demanding level, subject to specific MOE conditions and the school’s guidance. Do not promise that every pupil can choose any language level. Read the original grade and discuss the actual options.

The school should also confirm whether lessons for the child’s particular language are on campus or through an approved arrangement elsewhere. This may affect transport and CCA timing. Language learning deserves the same care as the school’s STEM opportunities when the family chooses its six schools.

What to ask about G3 Science laboratory learning

Parents often look for a school that says it is strong in Science, but the useful questions concern actual teaching. How are students introduced to laboratory safety? Do they learn to record observations honestly and to handle equipment under supervision? Are they taught to distinguish a measurement error from a scientific misconception?

A good practical lesson connects doing with thinking. A student may observe a change, record it in a table and then explain which concept is relevant. The pupil should learn why the conclusion follows from evidence rather than simply celebrate a visually interesting experiment. This process can develop both Science and mathematical reasoning.

Some schools have applied-learning activities in sustainability, technology, design or engineering. These can be valuable, but not every activity described on a website necessarily involves all Secondary 1 pupils. Ask what is common to the cohort and what requires selection for a special team.

The family should not conduct hazardous experiments at home to prepare for G3 Science. Safe observation, careful reading of published diagrams and discussion of variables are enough to practise scientific thinking outside a supervised laboratory.

How Kranji’s applied learning may appeal to STEM pupils

Kranji Secondary’s published Applied Learning Programme concerns design innovation for sustainable living. A pupil who likes Mathematics and Science may find opportunities to investigate a practical problem, measure a result and propose improvements. Communication and teamwork are part of such projects too, so English confidence may need developing alongside STEM knowledge.

The family should ask which activities every Secondary 1 pupil experiences, what the timetable commitment looks like and how the school assesses learning. An impressive school showcase does not prove that every child gets the same project or advanced enrichment opportunity.

Kranji’s historical PG2 cut-off of 24 places a score-24 pupil at the old boundary and a score-23 pupil one point better. The new cohort may have different demand. The school should be selected for its actual programme, teaching and a workable journey, not a promise implied by the previous endpoint.

A family living far from Choa Chu Kang should consider travel seriously. A pupil studying two demanding subjects needs enough time for reading, homework, CCA and rest. A more local school with suitable academic support can be a better fit for some students.

Greenridge and Queensway: PG2 endpoints of 25

Greenridge in Bukit Panjang and Queensway in Queenstown both recorded historical PG2 cut-offs of 25 for Secondary 1 entry in 2026. At score 24, the child was one point numerically better than those earlier endpoints; at score 23, two points better. This does not guarantee admission or mean the two schools are interchangeable.

Greenridge’s programmes and student leadership activities may interest a pupil who enjoys practical projects. Queensway has a different location and school environment. Parents should read the current school profiles, ask about Mathematics and Science lesson arrangements, and check what ordinary pupils can do beyond selected enrichment teams.

Both schools require consideration of actual travel. A family in Queenstown may find Queensway easy to reach, whereas another in Bukit Panjang may prefer Greenridge. A shorter commute can preserve energy for studying new algebra and scientific explanations.

Ask how teachers support pupils whose English and Mother Tongue are less secure. A school that gives clear, specific feedback across subjects may be a better match than one that merely appears more selective in a historical table.

Punggol Secondary, Edgefield and North Vista: North-East options

Punggol Secondary had a previous PG2 endpoint of 24, Edgefield 23 and North Vista 24. For a family living in Punggol or Sengkang, these may be realistic schools to investigate, depending on actual transport and the child’s interests. At score 24, Punggol Secondary and North Vista are at the historical boundary while Edgefield is a historic reach.

Families should verify each school’s current programmes, CCAs, general subject-level arrangements and support for pupils studying G3 Mathematics and Science from PG2. A pupil may enjoy a hands-on project but require clear instruction in English comprehension or Mother Tongue writing.

The comparison should not be framed as one school having better children because its previous cut-off was lower. A cut-off is an admissions result, not a measure of human worth or every lesson’s quality. The child should be helped to see schools as communities where they can learn and participate.

A local school can offer an important advantage: a predictable journey and more time for homework, rest and family activities. Parents should still weigh a genuinely distinctive programme at a more distant school if it is educationally meaningful, but recognise the daily cost.

Northbrooks, Riverside and the northern family decision

Northbrooks in Yishun had a previous PG2 cut-off of 25, while Riverside in Woodlands ended at 23. For a score-24 pupil, Northbrooks offers a one-point historical numeric margin and Riverside was beyond the earlier endpoint. That difference is helpful for planning but should not become a ranking of Mathematics or Science teaching.

The northern family should compare the actual school’s Maths curriculum, Science practical work, subject-level offers and co-curricular opportunities. Ask how students access help when an unfamiliar question appears and how teachers correct specific misconceptions. A STEM-strong pupil should be challenged meaningfully without neglecting language development.

Location matters too. A direct journey to a nearby school may make it easier for the child to attend CCA and complete assignments. An hour-long commute to a more selective school may impose a considerable weekly cost. Both family priorities and pupil interests belong in the choice.

Worked case: score 24 with Maths AL4 and Science AL5

Imagine Mathematics AL4, Science AL5, English AL7 and Mother Tongue AL8, totalling 24. The child enjoys problem-solving and practical experiments but finds lengthy English instructions and formal Mother Tongue writing hard. Some relatives suggest applying through PG3 because the two strongest subjects could be G3.

The primary-school teacher clarifies that the ordinary posting route remains PG2, while the Standard Maths and Science grades meet the subject-specific threshold for potential G3 offers. The family researches PG2 schools and asks how those higher subjects will be supported alongside G2 English and Mother Tongue.

The parents compare a school whose earlier PG2 cut-off was 24 with one ending at 25. They explain the difference accurately as a historical boundary versus a one-point numerical margin. They also test the school journey and listen to the child’s interest in a project-based activity. No option is described as guaranteed.

After posting, the family confirms the two actual subject offers and helps the child organise a timetable. The goal is to develop STEM strengths while improving language skills, not to make the child prove that a strong PSLE grade eliminates every future difficulty.

Worked case: score 23 with Maths AL5 and Science AL5

Another pupil receives Mathematics AL5, Science AL5, English AL6 and Mother Tongue AL7, totalling 23. The child is interested in Mathematics but sometimes rushes written answers and has difficulty explaining scientific processes precisely. The family knows the pupil may be eligible for higher Maths and Science, yet also wants a school where feedback is clear.

They investigate local PG2 schools with historical endpoints of 23, 24 or 25, giving different previous numerical comparisons. They ask teachers what pupils do when their answer contains a conceptual mistake, how laboratory safety is taught and whether reading support is available when required.

The child likes one school’s sports CCA and another’s applied-learning activity. Parents take both interests seriously, because school life is more than the two examined strengths. They choose six acceptable schools and rank genuine preferences without making promises about admission.

The pupil starts Secondary 1 understanding that G3 Mathematics and Science will involve unfamiliar ideas and that asking for help is a sign of effective learning. The family celebrates curiosity and accuracy rather than expecting effortless excellence.

How to make the six school choices responsibly

First confirm the exact PSLE total and individual Standard grades. For scores 23 and 24, use the ordinary Posting Group 2 admission route, not PG3. Make a geographical longlist of schools whose PG2 historical score range and programmes can reasonably be considered.

For each school, write its current official name, previous PG2 cut-off, location, CCA options, Science and Mathematics programmes, language support and one reason the child would genuinely want to attend. Remove any institution that the family could not realistically reach or whose required subjects are unavailable. Be careful with similarly named schools, such as Dunman Secondary and Dunman High.

Select six genuine preferences. MOE generally advises two or three schools whose previous cut-off is numerically higher than the child’s score when feasible. At score 24, a previous PG2 endpoint of 25 is a one-point margin, not a guarantee. A school ending at 23 was a historical reach and should not be labelled safe because the family likes its name.

Rank according to true preference. Where students have the same PSLE total and compete for a final place, citizenship, school-choice order and computerised balloting may determine the result. Ranking a less preferred school first does not create an automatic advantage over pupils with better scores. Make the list balanced and honest first.

If a pupil has a confirmed DSA-Sec place, follow the official separate arrangements. After normal posting, subject-level offers for G3 Maths and Science may require another response. Keep school admission and individual class-level decisions clear so the family does not miss important instructions.

A four-week plan for the start of Secondary 1

In week one, read the official posting and subject-level offer letters, check booklists and learn how the child moves between classes. Ask which teachers can help when a new Maths or Science topic is confusing. Build a simple homework planner that includes CCA and travel time.

During the second week, practise mathematical structure. Ask the pupil to explain the meaning of a variable in a simple equation, show why an operation preserves equality and check an answer by substitution. If fractions are insecure, return to visual models and concrete examples. Short, thoughtful practice is better than many rushed tasks.

In week three, practise Science explanation. Use a school text or safe observation to identify the question, variables, evidence and conclusion. Ask whether the explanation goes beyond what the data show. Encourage the pupil to write two or three clear sentences rather than a memorised page of keywords.

In week four, review the whole timetable. Are English and Mother Tongue progressing, and is the child making friends and sleeping well? Is the journey manageable after CCA? If the new G3 subjects require extra support, bring specific examples to the school. The goal is sustainable learning, not proof that the pupil will never struggle in a strong subject.

Questions worth asking at an open house

• Can eligible PG2 pupils with Standard Mathematics and Science AL5 or better be offered both subjects at G3?
• How are the offers communicated and what must parents do to accept or review them?
• How does the school teach algebra, directed numbers, fractions and mathematical reasoning in Secondary 1?
• What laboratory safety, graph-reading and evidence-based Science teaching does every pupil receive?
• What support is available when a pupil is strong in Maths and Science but less secure in English or Mother Tongue?
• Which STEM, environmental or technology projects are for all pupils and which require selection?
• How are mixed form classes, CCA and student wellbeing organised?
• What time does the school day begin and how does the pupil return after late CCA?
• Can a family learn what criteria guide later subject-level adjustments?

Frequently asked questions

Can a score-24 pupil with Maths and Science AL5 enter PG3?

No, not through the ordinary total-score posting route. A score of 24 is PG2. The child may still be eligible for individual G3 Maths and Science offers.

Can a PG2 pupil take both Maths and Science at G3?

Standard AL5 or better in each relevant subject meets the usual eligibility criterion for a G3 offer from the indicative G2 start. The receiving school must confirm the actual offers.

Does strong Maths automatically make the child good at Science?

No. Numerical skills can help with graphs and measurements, but scientific concepts, fair tests and evidence need their own teaching.

Do two G3 subjects improve admission to a PG3 school?

No. The school posting group is based on the overall score and applicable options, while G3 refers to levels of individual subjects.

Is a prior PG2 cut-off of 25 a guarantee for score 24?

No. It provides a one-point historical numerical margin, but new school choices, vacancies and tie-breakers can change the result.

Should families choose schools based only on STEM awards?

No. Verify what ordinary students learn, access to programmes, language support, school culture, CCA and transport. Awards do not describe every child’s educational experience.
