Close the gaps now, so P6 is not a scramble

P4 and P5 are not just harder sums. They are structural shifts in how a child has to think. When the foundation underneath is partial, the new demands quietly surface the gap.

Expedite is how a Primary 4 or Primary 5 child joins us between January and May. Your child joins our regular weekly class for their level, you pay once for every lesson left in 2027, and we unlock last year's full course on our LMS within a few working days of payment, so your child can fill last year's gaps while keeping pace with this year. It starts with a free diagnostic.

How Expedite builds P4–P5 foundations

Why P4 and P5 matter

P4 and P5 shift in structure, not just difficulty.

Most parents assume these years are "more of the same, but harder." The real change is in how a child has to reason.

At P4 the syllabus introduces abstract ideas and multi-step problems. At P5, much of the PSLE syllabus arrives at once: ratio, percentage, rate and average, with questions that combine concepts. Where the earlier foundation is secure, a child builds forward. Where it is partial, they spend the year quietly revisiting what came before, and the time for new learning narrows.

At P4

Factors and multiples, multi-step problems, choosing a method, and complex model drawing.

At P5

Ratio, percentage, rate and average arrive, with combined-concept questions and faster working.

Diagnostic patterns

Five places where the gap usually shows.

These are the topics that most often reveal an underlying weakness. The diagnostic looks here first, so support is aimed at the cause, not just the symptom.

Fractions

Equivalent fractions, unlike denominators, and "fraction of remainder" problems. This is the structural base for P5 ratio, percentage and rate.

Multi-step word problems

Choosing the operation, breaking a problem into steps, and working backwards. The same decomposition logic runs through every P5 and P6 word problem.

Model drawing

Knowing when a model is the right method, drawing it accurately, and turning a finished model into calculation. The central method in Singapore Math.

Problem-solving heuristics

Classifying which heuristic fits, staying systematic on unfamiliar formats, and checking that an answer is reasonable.

Decimals

Place value, converting with fractions, and keeping units consistent. Decimals appear across a large share of P5 and P6 questions.

"Worth noticing at home: homework taking longer than last year, more 'careless' mistakes, or 'I'm just bad at Math'."

The pattern we see

Why "let's wait and see" rarely closes a structural gap.

Waiting works when a gap is small or situational. When it is structural, where a child is missing the understanding each new topic builds on, the same months slip past while the syllabus keeps moving.

January

"Let's see how they settle into the new year."

March

First assessment comes back around AL4 to AL5. "Give it more time."

June

Mid-years still AL4 to AL5. "We'll look at it after the holidays."

July

Preferred classes are filling. The options are narrower than in January.

September

End-of-year exams arrive, and the grade has not meaningfully shifted.

Naming this is not pressure. If the gap is minor, we will tell you so, and point you to lighter support. The point of starting earlier is simply that more of the year is still ahead.

Diagnosis first

Not every child needs Expedite.

We lead with assessment, not the product. A free diagnostic places your child on one of three honest paths, and Expedite is only one of them.

Path 1

Secure foundations

A child at AL1 to AL2 with strong, consistent foundations, where the family can support structured practice at home.

Often needs no regular programme yet, or lighter targeted practice closer to PSLE.

Path 2

Minor, localised gaps

A child at AL2 to AL3 with a small, contained gap, who wants guided weekly practice rather than remediation.

A good fit for our Primary Math Weekly class.

Path 3 · Expedite

Structural, multi-topic gaps

A child at AL3 to AL6 with gaps across more than one topic, who needs gap-filling and forward progress, with a clear two to three year plan toward PSLE.

This is what Expedite is built for.

Many families place themselves in Path 3 when Path 2 is enough, and the other way around. That is exactly why the diagnostic comes first.

What the year includes

The same weekly class, paid once, with last year built in.

Expedite is not a separate class. Your child attends the same weekly P4 or P5 class as every other GPA student at that level. What Expedite changes is how you join and pay, and what you get at the start.

Every remaining 2027 lesson, from your child's first lesson to the end of the year: the weekly term-time lessons and the CORE+ lessons in the March, June, September and year-end holidays. P4 has 51 lessons in 2027 (1.5 hours each) and P5 has 53 (2 hours each).
Every lesson recorded. Recordings usually go up on our LMS about a week after the lesson, so a missed week is never a missed concept.
Weekly marked homework and an end-of-term assessment each term, reviewed with your child in class.
Our own textbooks and workbooks for the lessons covered, written and published in-house.
Last year's full course on our LMS, activated within 3 working days of payment. More on this below.

The distinctive part

The Time Machine: last year's lessons, available from the start.

You cannot fix a P5 gap with only P5 lessons. The gap usually lives a year earlier.

Every Expedite child gets LMS access to the previous primary year's full course from our 2026 programme: the recordings and the materials. A P4 child can quietly fill P3 gaps while attending P4 class; a P5 child does the same with P4. It is self-paced and activated within 3 working days of payment, so the foundation is rebuilt in parallel rather than left behind. Access runs to 31 December 2027.

P4 Expedite

The full P3 2026 course on our LMS, recordings and materials, to close P3 gaps.

P5 Expedite

The full P4 2026 course on our LMS, recordings and materials, to close P4 gaps.

Joining from Term 2 (first lesson on or after 22 March 2027)? Your child gets this year's Term 1 recordings and materials for their own level instead, so the lessons they missed are covered first.

How we teach

Diagnosis, not more of the same.

Expedite is not "extra practice on top." The plan is shaped by what the diagnostic and weekly marking reveal, and lessons advance on understanding, not a fixed pace.

It starts with a diagnosis

We find which of the five gap areas are open before we plan anything, so support is aimed at the cause.

Marking that teaches self-diagnosis

Homework is marked every week. The marking names the error pattern and points to a cleaner approach, so a child learns to spot it themselves.

Small enough to track everyone

Classes are kept small, capped where possible at 6 at Bukit Timah and 8 at Punggol and Pasir Ris, so the tutor sees every child's working in the lesson.

Who it suits

A good fit, and an honest "not yet".

Expedite is a strong fit when your child:

is scoring around AL3 to AL6 with gaps across more than one topic;
needs both gap-filling and forward progress at the same time;
takes longer on homework than last year, or makes more "careless" slips;
is starting to say "I'm bad at Math", with confidence quietly dropping;
has a family ready to commit to weekly attendance and steady practice.

Already secure

An AL1 to AL2 child may not need a programme yet. We will say so, and suggest lighter practice closer to PSLE.

A small gap

A minor, contained gap is usually better served by our weekly class, paid term by term.

Wants fast, effortless results

Expedite rewards consistent effort. If a family is not ready for that, we would rather be upfront.

Schedule, format & fees

Join between January and May.

P4 Expedite

Weekly 1.5-hour lessons · 51 lessons in 2027 · Bukit Timah, Punggol or Zoom

P5 Expedite

Weekly 2-hour lessons · 53 lessons in 2027 · Bukit Timah, Punggol, Pasir Ris or Zoom

Venues

The same curriculum and materials at every branch and on Zoom. Your child keeps one fixed weekly class. If they are unwell or busy one week, they can join that lesson on Zoom with a day's notice. If you are thinking of Zoom for the whole year, talk to us first: it suits children who work independently. See the 2027 timetable →

When to join

Expedite is open to children joining from January to May 2027. January gives the most runway. A child joining from Term 2 gets this year's Term 1 recordings and materials, so the lessons already held are covered. From June, new P4 and P5 students join our weekly class and pay term by term.

One payment for the rest of 2027

P4 Expedite

$3,672

2027 intake

P5 Expedite

Questions parents ask

How is Expedite different from the regular weekly class?

It is the same class. An Expedite child attends our regular weekly P4 or P5 class, including the CORE+ holiday lessons. The difference is how you join and pay: Expedite is for children joining between January and May 2027, it is paid once for every remaining 2027 lesson at a programme discount, and it unlocks last year's full course on our LMS within 3 working days of payment. It replaces the weekly class fee; you never pay for both.

What is the Time Machine?

It is LMS access to the previous primary year's full course from our 2026 programme, recordings and materials. A P4 child gets the P3 course and a P5 child gets the P4 course, so they can close last year's gaps while keeping pace with this year. It is self-paced, activated within 3 working days of payment, and available until 31 December 2027. A child whose first lesson is on or after 22 March 2027 gets this year's Term 1 recordings and materials for their own level instead.

How much does Expedite cost?

The fee is every remaining 2027 lesson from your child's first lesson, at the per-lesson rate for the class, less a programme discount of 10% if paid by 31 March 2027 (8% by credit card) or 5% from 1 April to 31 May (3% by card), and less any branch discount. For a standard class at Bukit Timah paid by PayNow, P4 Expedite is $3,672 and P5 Expedite is $4,770 for a January start, and the fee steps down for later months. New students also pay a $100 registration fee and a $100 materials fee, both waived for families who register for 2027 by 31 December 2026. The fee is paid in full at registration and is non-refundable.

Does my child actually need Expedite?

Not every child does. We start with a free diagnostic and place your child on one of three honest paths. A child with secure foundations may need nothing yet; a child with a small, contained gap is usually better served by our weekly class, paid term by term; Expedite is for structural gaps across more than one topic. We lead with the assessment, not the product.

When can my child join?

Expedite is open to children joining from January to May 2027. January gives the most runway and the most lessons. From June, new P4 and P5 students join our weekly class and pay term by term.

How large are the classes, and who teaches them?

Classes are kept small: where possible, we cap them at 6 students at Bukit Timah and 8 at Punggol and Pasir Ris (holiday, assessment and Zoom-only lessons can be larger). Every class teaches the same GPA curriculum and materials, written in-house under our founder, Mrs Eileen Toh, and your child's tutor is confirmed with their class.

My child has become anxious about Math. Will this help?

Small classes let lessons move at the pace of understanding, and errors are treated as useful information rather than failures. Confidence tends to return as competence deepens. The weekly marking is written to show a child what to fix, not just what was wrong.
