The 0606 exam, grades & tutoring

0606 Command Words Decoded: Show, Find, Solve, Determine, Prove →

What does 'hence' mean in an Add Math question?
Use the result of the previous part. If part (i) says 'show that…' and part (ii) says 'hence solve…', a solution that ignores part (i) usually scores little or nothing. 'Hence or otherwise' permits another route, but 'hence' is nearly always faster.
What's the difference between 'show that' and 'prove'?
In practice both demand complete visible reasoning. 'Show that' typically gives you the destination (verify it with full steps); 'prove' is most common with identities and requires transforming one side into the other without ever treating it as an equation.
Does 'write down' mean I need working?
No, 'write down' or 'state' signals the answer is available by inspection and carries no method marks. Spending five lines deriving it wastes time; just state it.

Add Math Tuition Cost in Malaysia: What You Should Pay →

How much does IGCSE Add Math tuition cost per hour in Malaysia?
Typical ranges: group tuition centres RM30–60 per hour equivalent; private 1-to-1 with an experienced specialist RM70–150 per hour online, and RM100–200+ in-person in KL. University students charge RM30–50 but rarely know the 0606 exam layer.
Is group or 1-to-1 tuition better for Add Math?
For a method-heavy subject where the value is in having your written working corrected, 1-to-1 moves grades faster per hour. Group classes suit students who are already solid and need volume practice with light guidance.
Why do IGCSE tutors cost more than SPM tutors?
Smaller supply of tutors who genuinely know Cambridge syllabuses and mark schemes, and most IGCSE families are at international schools where tutors price accordingly. Paying IGCSE rates for a tutor who only knows SPM Add Maths is the worst of both.

Add Math vs IGCSE Math: 0606 and 0580 Compared →

Is Add Math a replacement for IGCSE Math?
No. Additional Mathematics 0606 is taken alongside IGCSE Mathematics 0580, not instead of it. Universities and sixth forms expect a standard maths IGCSE; Add Math is the extension on top.
How much harder is 0606 than 0580?
Most students experience a full step up. 0580 Extended ends roughly where 0606 begins. 0606 then adds calculus, logarithms, trig identities, permutations and combinations, and more, examined with single-tier papers and no formula sheet for most results.
Do both subjects appear separately on the certificate?
Yes. They are separate IGCSE subjects with separate grades. A strong 0580 grade plus a strong 0606 grade is one of the most convincing quantitative signals a 16-year-old can show.

Differentiation in IGCSE Add Math: Exam Technique That Scores →

How many marks is differentiation worth in 0606?
Calculus is the largest topic in the syllabus and differentiation appears on both papers every session, directly, and inside tangents/normals, stationary points, rates of change and kinematics questions. Across a typical session it underpins 20–30 marks.
Do I need to state which rule I'm using?
You don't need to name it, but you must show it: write u and v (or the chain decomposition) explicitly before differentiating. That visible setup line is usually where the first method mark lives.
What's the most common differentiation mistake in 0606?
Sign and bracket errors inside the quotient and chain rules, and on applications, differentiating correctly but forgetting to substitute the x-value, or finding a tangent gradient when the question asked for the normal.

Every Formula and Identity to Memorise for IGCSE Add Math →

Does IGCSE Add Math give you a formula sheet?
The question paper provides only a minimal list (such as the quadratic formula, binomial expansion form, and arc/sector formulas may appear in the front matter depending on the syllabus year). Treat everything on this page as memorise-or-lose-marks, especially the trig identities and calculus rules, which are never given.
What's the fastest way to memorise Add Math formulas?
Use them, don't recite them. Two formula-recall drills a week, write the whole list blank-page from memory, check, mark gaps, plus normal practice questions embeds the list in about a month. Our memorisation guide covers the method in detail.
Which formulas matter most for Paper 1?
Exact trig values, the quadratic formula, completing-the-square form, log laws and differentiation rules, because on the non-calculator paper you cannot brute-force around a forgotten formula.

From Add Math to A Level Maths: The Bridge Explained →

Do I need Add Math to take A Level Maths?
Formally, no, schools admit students to A Level Maths from 0580 alone, usually requiring an A. Practically, students arriving without 0606 meet calculus, logarithms, and trig identities for the first time at A Level pace, and the first term is consistently the hardest of their school career.
How much of A Level Maths does Add Math cover?
A large share of AS Pure Mathematics appears in 0606 in earlier form: differentiation and integration, logs and exponentials, trig identities and equations, binomial expansion, APs/GPs, coordinate geometry including the circle, and vectors. The A Level adds depth and new applications, but the conceptual first contact has already happened.
Does Add Math help with IB or other pathways?
Yes, the same content underpins IB Mathematics (especially AA HL), STPM mathematics, A Level Further Maths entry, and matriculation programmes. Any quantitative pathway benefits from meeting calculus before 17.

How to Choose an IGCSE Add Math Tutor (What Actually Matters) →

Should the tutor specialise in 0606 specifically?
Yes, and this is the most-skipped check. Add Math has its own mark schemes, command words and a non-calculator paper, a tutor who mainly teaches SPM Add Maths or general IGCSE maths will be solid on content but miss the exam-technique layer where 0606 grades are decided.
Is a more expensive tutor better?
Price correlates weakly with results in Malaysian tutoring. What predicts outcomes: subject specialisation, whether the tutor marks homework against real mark schemes, and structured weekly feedback. Judge those in a trial class, not the rate card.
Online or in-person tutor for Add Math?
For a working-heavy subject like Add Math, a good online setup (shared whiteboard, written working visible to both sides) matches in-person teaching, and widens your choice from tutors-near-me to the best specialist available. The trial class will tell you whether the format suits your child.

How to Get an A* in IGCSE Add Math (0606) →

What percentage do you need for an A* in IGCSE Add Math?
Cambridge does not publish a fixed percentage, thresholds move each session, but an A* in 0606 has typically required roughly 85% or higher across both papers. Aim your practice at 90% so the moving boundary never decides your grade.
How long does it take to go from a B to an A* in Add Math?
With two focused sessions a week plus past-paper practice, most students need three to six months. The limiting factor is usually working habits, not understanding, fixing how you set out solutions pays off fastest.
Which topics matter most for an A* in 0606?
Calculus is the largest topic and appears across both papers, followed by trigonometry and quadratics. But A* students lose their marks on presentation, showing working, exact values on Paper 1, and answering the command word, more than on any single topic.

How to Show Working for Full Marks in IGCSE Add Math →

Can I get marks with the wrong final answer?
Yes, usually most of them. A typical 5-mark 0606 question carries 3 method marks and 2 accuracy marks; correct method with one arithmetic slip commonly keeps 3 or 4 of the 5. This is why working habits matter more than perfection.
Do examiners really read all the working?
Yes. 0606 mark schemes instruct examiners to award method marks wherever the relevant step is seen. Working that is legible and in order gets the benefit of every doubt; scattered fragments often don't.
Should I cross out wrong attempts?
Only if you've replaced them. A crossed-out attempt is not marked, but an uncrossed wrong attempt alongside a right one can cause both to be reviewed. If you make a second attempt, clearly cross out the first.

IGCSE Add Math 0606 Exam Format Explained →

What calculator is allowed in 0606 Paper 2?
A standard scientific calculator is expected for Paper 2. Graphic display calculators are not required, and calculators with computer algebra (CAS) are not permitted. No calculator of any kind is allowed in Paper 1. Check your school's exam-officer guidance for approved models.
When are the 0606 exams held in Malaysia?
Cambridge runs IGCSE exam series in May/June and October/November, and Malaysian international schools enter students in both. Your school confirms which series you sit; most Malaysian schools use May/June.
Is there a Core and Extended tier in Add Math?
No. Unlike IGCSE Mathematics 0580, Additional Mathematics 0606 has a single tier, every student sits the same two papers and the full A*–E grade range is available to everyone.
Can private candidates sit 0606 in Malaysia?
Yes. Private candidates can register through British Council Malaysia or a Cambridge-registered school that accepts external candidates. Since 0606 is entirely written papers with no coursework or practical, it is straightforward to enter privately.

IGCSE Add Math Grade Boundaries Explained →

What mark do you need for an A* in 0606?
It changes every session because thresholds are set after marking, but A* has typically required roughly the mid-80s as a percentage of the 160 total marks, around 135 or higher. Treat 90% as your practice target so the moving line never matters.
Where can I find official 0606 grade thresholds?
Cambridge publishes grade threshold tables for each exam series on cambridgeinternational.org shortly after results. Search for 'grade thresholds 0606' plus the session, e.g. 'June 2024'.
Are Add Math grade boundaries lower than other subjects?
Often yes, as a percentage, because 0606 is a single-tier paper that must stretch to A*, the thresholds for middle grades tend to sit lower than in tiered subjects. A 60-something percent can be a respectable grade in a hard session.

IGCSE Add Math Non-Calculator Paper: The Complete Guide →

Is the whole IGCSE Add Math exam non-calculator?
No, only Paper 1. Paper 2 allows a scientific calculator. Each paper is worth 50% of the final grade, so half your marks are earned without a calculator.
What kinds of numbers will Paper 1 questions use?
Questions are written to have manageable arithmetic: answers come out in exact forms, fractions, surds, multiples of π, or values like ln 3. If your working is producing ugly decimals on Paper 1, that is usually a sign of a method error.
How should I practise for the non-calculator paper?
Do a portion of every practice session calculator-free, even on topics you know well. Rebuild fraction and surd arithmetic, memorise exact trig values, and practise leaving answers in exact form. Ten minutes of daily mental-arithmetic drills for six weeks makes a visible difference.

IGCSE Add Math Past Papers: How to Use Them Properly →

Where can I download 0606 past papers free?
Cambridge publishes recent papers on its website, and most schools provide full archives through their exam portals. Several well-known revision sites also host complete 0606 paper and mark-scheme collections, your school's maths department will have everything regardless.
Are old 0606 past papers still relevant for 2025–2027?
Mostly yes, with two adjustments: skip dedicated indices/surds questions (no longer taught content, though the skills still appear inside other questions), and note that older papers allowed calculators on both papers, so redo older Paper 1s under non-calculator conditions. Coordinate geometry of the circle won't appear in older papers at all, so source recent or specimen material for it.
How many past papers should I do before the exam?
Quality over count: eight to twelve full papers done timed and properly marked beats twenty done casually. The marking and error-logging step is where the improvement happens.

Integration and Area Under a Curve: 0606 Exam Technique →

Do I lose a mark for forgetting +c?
For indefinite integrals, yes, the constant of integration is part of the answer and omitting it costs the accuracy mark. In definite integrals the constant cancels, so no +c is needed once limits are attached.
How do I know when area questions need splitting?
Whenever the curve crosses the x-axis inside your limits, or the region is bounded by a curve and a line. Sketch first: a 30-second sketch shows whether you need separate integrals or a subtraction of functions.
Is integration tested on the non-calculator paper?
Yes. Both papers can test any topic, and Paper 1 regularly carries an integration or area question with friendly numbers, answers typically come out as exact fractions.

Is Add Math Hard? What Makes 0606 Difficult (and Manageable) →

Is Add Math the hardest IGCSE subject?
It is consistently rated among the most demanding IGCSEs, mainly for its content level (AS-grade material at 16) and time appetite. But its difficulty is unusually structured, method-based, predictable question types, which makes it more trainable than subjects that demand originality.
Which Add Math topic is the hardest?
Students most often name trig identity proofs, the harder calculus applications (connected rates), permutations and combinations word problems, and relative velocity in vectors. Notably, all four are method topics, hard until the routine is drilled, then reliable.
Can an average maths student pass Add Math?
A student at a solid B in IGCSE Maths, practising consistently 3+ hours a week with feedback on their working, typically lands B or above in 0606. Below that foundation, the honest answer is to strengthen algebra first or reconsider taking it.

Should I Take Add Math? An Honest Guide for IGCSE Students →

What grade in IGCSE Maths do I need before taking Add Math?
There is no official requirement, but in practice students working at a solid A in IGCSE Mathematics 0580 (or its equivalent) cope well. Students at a B can succeed with consistent support; below that, the algebra load of 0606 usually makes the subject punishing.
Can I switch from 0580 to 0606 mid-year?
Add Math is normally taken alongside 0580, not instead of it. Joining the 0606 class mid-year is possible if your algebra is strong, but you will need a catch-up plan for the topics already covered, this is one of the most common reasons families come to us.
Is Add Math worth it if I'm not doing A Level Maths?
It carries less direct benefit, but it still signals quantitative ability to universities and keeps STEM doors open. If you are certain you're heading to arts or humanities pathways, the effort may be better spent maximising other grades.
What happens if I fail Add Math?
An ungraded 0606 result does not affect your other IGCSE grades, each subject is certificated separately. But rather than gambling, decide early: students who are honest about their algebra level by mid-Year 10 either build it up in time or redirect the effort.

The 8-Week IGCSE Add Math Revision Plan (Free) →

How many hours a week does this plan need?
Around 5–6 hours: three or four study blocks of 60–90 minutes. It is built for a student still attending school with other subjects to revise, not a maths-only bootcamp.
What if I have less than 8 weeks?
Compress from the front, not the back. Merge weeks 1–4 (topic revision) proportionally, but protect weeks 5–8, the paper-practice phase is where grades actually move. With 4 weeks left, do one week of weak-topic triage then three weeks of papers.
Can I use this plan for the November session?
Yes. The plan is session-agnostic, start it 8 weeks before your first paper, whether that's May/June or October/November.

The Most Common IGCSE Add Math Exam Mistakes (and Fixes) →

What is the single most common mistake in 0606?
Insufficient working, students doing steps mentally and writing only answers, which forfeits method marks wholesale. It outranks any mathematical misunderstanding in examiner reports.
How do I stop making careless mistakes in Add Math?
Careless errors are usually systematic, the same two or three types repeating. Log every dropped mark from practice papers by cause for three weeks; the pattern that emerges is fixable with a targeted habit, unlike generic 'check your work' advice.
Do you lose marks for not simplifying answers?
Sometimes. If the question specifies a form ('in its simplest form', 'in the form a + b√3'), the final accuracy mark attaches to that form. If no form is specified, an unsimplified but correct exact answer usually scores.

Trig Identities and Equations: How to Score in 0606 →

How do I start a trig identity proof?
Start from the more complicated side and simplify toward the other, never work on both sides at once or move terms across the identity. Convert everything to sin and cos first when stuck; it resolves the majority of 0606 identity proofs.
Why do I keep losing marks on trig equations?
Almost always missing solutions: forgetting the second solution in the range, dividing by cos θ instead of factorising (which deletes solutions), or working in degrees when the range is in radians. Check the range's units before anything else.
Is the R-formula examined every year?
It appears in most sessions, either directly ('express in the form R sin(θ + α)') or as the setup for solving an equation or finding a maximum. It is one of the most predictable high-mark questions in the syllabus, learn the routine and it's reliable marks.

The 14 syllabus topics

Functions →

What's the difference between fg(x) and gf(x)?
Order matters and is read right to left: fg(x) means apply g first, then f, substitute g(x) into f. Computing them in the wrong order is the most common composite-function error in 0606 scripts.
How do I find the domain of an inverse function?
The domain of f⁻¹ is the range of f, and the range of f⁻¹ is the domain of f. So find the range of the original function first, usually from a sketch or completed-square form, then swap.
Why must a function be one-one to have an inverse?
An inverse must send each output back to exactly one input. If two inputs share an output (like x² with ±2 → 4), reversing is ambiguous, so no inverse exists unless the domain is restricted to make the function one-one.

Quadratic Functions →

When should I complete the square instead of using the formula?
Complete the square when the question wants the vertex, the maximum/minimum value, the range, or the 'express in the form a(x+p)²+q' format. Use the formula (or factorising) when it just wants solutions. The question's wording chooses the method for you.
What does the discriminant tell you about a line and a curve?
Substitute the line into the curve to get a quadratic, then b²−4ac: positive means two intersection points, zero means the line is a tangent, negative means they never meet. Stating this conclusion in words is usually a mark.
How do I solve a quadratic inequality?
Always sketch. Solve the equality to find the roots, draw the parabola, then read off where it is above or below zero. Answering from algebra alone, flipping signs by memory, is where the wrong-region errors come from.

Factors of Polynomials →

What's the difference between the remainder theorem and the factor theorem?
The remainder theorem says dividing p(x) by (x − a) leaves remainder p(a). The factor theorem is its special case: if p(a) = 0, the remainder is zero, so (x − a) is a factor. One theorem, two uses.
Why do I substitute x = −2 for the factor (x + 2)?
Because the theorem uses the value that makes the factor zero: x + 2 = 0 gives x = −2. Substituting +2 instead of −2 is the single most common error in this topic.
Do I have to use long division to factorise a cubic?
No, comparing coefficients or inspection is usually faster and equally accepted. Find one root by trial, write the cubic as (x − a)(quadratic), then determine the quadratic's coefficients by matching terms.

Equations, Inequalities and Graphs →

How do I solve |2x − 1| = |x + 4|?
Two reliable routes: square both sides (moduli vanish, solve the resulting quadratic), or set 2x − 1 = ±(x + 4) and solve both linear equations. Either way you get two solutions; check both in the original if the question mixes modulus with non-modulus terms.
When does a modulus equation have no solutions?
Whenever it forces a modulus to equal a negative number, |ax + b| = k has no solutions for k < 0. Spotting and stating this is sometimes the whole question.
How do I solve a cubic inequality from its graph?
Factorise to find the roots, sketch the cubic through them (noting the sign of the x³ coefficient), then read the x-regions where the curve sits above or below the axis. The answer is written as a union of intervals.

Simultaneous Equations →

Which equation do I substitute from?
Always rearrange the linear equation (it's the one without squares) to make x or y the subject, then substitute into the non-linear one. Choose whichever variable gives the cleaner expression, avoid fractions where possible.
How many solutions should I expect?
Up to two pairs, because the substitution produces a quadratic. Geometrically: the line crosses the curve at two points, touches at one (tangent), or misses entirely. Each x must be paired with its own y.
Why do I keep getting the right x-values but wrong y-values?
Almost certainly substituting back into the quadratic instead of the linear equation, or pairing the values wrongly. Always find y from the linear equation, and present answers as coordinate pairs.

Logarithmic and Exponential Functions →

What's the relationship between e^x and ln x?
They are inverse functions: ln(e^x) = x and e^(ln x) = x. Graphically each is the other reflected in y = x. Most 0606 e/ln equation questions are solved by applying one to undo the other.
Why must I check solutions to log equations?
Because logarithms are only defined for positive arguments. Algebra can produce values that make an original log argument zero or negative, those must be rejected with a stated reason, and the rejection is typically worth a mark.
What is 'reducing to linear form' actually for?
It converts curved experimental relationships like y = ax^n or y = Ab^x into straight lines (log y against log x, or log y against x), so the constants can be read from a gradient and intercept. It's one of the most predictable multi-mark questions in 0606.

Straight-Line Graphs →

What's the fastest form for the equation of a line in Add Math?
y − y₁ = m(x − x₁). One point and a gradient go straight in with no intercept-solving step. Rearrange to whatever form the question requests at the end.
How do I find a perpendicular bisector?
Midpoint of the segment + negative reciprocal of its gradient, then y − y₁ = m(x − x₁) through the midpoint. Both ingredients (midpoint, perpendicular gradient) carry separate marks, show each explicitly.
What is the shoelace formula and can I use it?
The array method for the area of a polygon from its vertices, fully accepted in 0606 and expected for 'area of rectilinear figure' questions. List vertices in order (anticlockwise), repeat the first at the end, cross-multiply and halve.

Coordinate Geometry of the Circle →

Is coordinate geometry of the circle new to IGCSE Add Math?
Yes, it was added to the 0606 syllabus for examinations from 2025. Because old past papers don't contain it, use specimen papers and recent sessions for practice, and expect it to be examined: new topics reliably are.
How do I find the centre and radius from x² + y² + 2gx + 2fy + c = 0?
Centre (−g, −f), radius √(g² + f² − c), or, more reliably under pressure, complete the square in x and y to reach (x−a)² + (y−b)² = r² and read them off. The completing-the-square route also shows the working marks.
How do I show a line is tangent to a circle?
Two accepted methods: substitute the line into the circle and show the discriminant is zero, or show the perpendicular distance from the centre to the line equals the radius. The discriminant route uses familiar machinery and is usually safer.

Circular Measure →

Why do the formulas only work in radians?
Because s = rθ and A = ½r²θ are derived from the definition of the radian (arc equals radius when θ = 1). Feed them degrees and the answers are wrong by a factor of about 57. Convert first, every time.
How do I convert between degrees and radians?
π radians = 180°. Degrees → radians: multiply by π/180. Radians → degrees: multiply by 180/π. On Paper 1, answers stay as exact multiples of π.
What does a typical 0606 circular measure question look like?
A composite diagram, sector plus triangle, or a shaded segment, asking for perimeter and area. The skill is decomposing the region into sector pieces and triangle pieces, then adding or subtracting.

Trigonometry →

Do I need to memorise the exact trig values?
Yes, instantly. Paper 1 is non-calculator, and exact values of sin, cos and tan at 0°, 30°, 45°, 60°, 90° (and their radian forms) are assumed working knowledge. The two special triangles let you re-derive them if memory blanks.
What are amplitude and period?
For y = a sin(bx) + c: amplitude is |a| (the height from centre line to peak), period is 360°/b (or 2π/b in radians), how far before the wave repeats. The constant c shifts the centre line. These read directly off the equation, and stating them is often a write-down mark.
Which trig identities does 0606 expect?
tan θ = sin θ/cos θ, sin²θ + cos²θ = 1 and its two divided forms (1 + tan²θ = sec²θ, 1 + cot²θ = cosec²θ), the reciprocal definitions of sec, cosec and cot, and the R-formula a sin θ ± b cos θ = R sin(θ ± α). None are given in the exam.

Permutations and Combinations →

How do I know whether to use nPr or nCr?
Ask one question: does the order of the chosen items matter? Arranging people in a row, forming numbers, assigning distinct roles, order matters, use nPr (or factorials). Choosing a committee, a team, a subset, order doesn't, use nCr.
Why do restrictions get handled first?
Because the restricted positions or people have fewer choices, and choices multiply. Seat the constrained item first ('the letter must end in A'), then count the freedoms left. Restriction-last counting almost always double-counts.
What does 'at least one' signal?
Complement counting: total arrangements minus the arrangements with none. Computing 'at least one' directly means adding many cases; subtracting the single 'none' case is faster and safer.

Series →

How do I find a specific term in a binomial expansion without expanding everything?
Use the general term nCr aⁿ⁻ʳ bʳ. Set up the power condition you need (e.g. the x³ term, or the term independent of x), solve for r, then evaluate that single term, coefficient and sign included.
What's the difference between an AP and a GP?
An arithmetic progression adds a constant difference d each step; a geometric progression multiplies by a constant ratio r. Test by subtracting consecutive terms (constant → AP) or dividing them (constant → GP).
When does sum to infinity exist?
Only for a GP with |r| < 1, the terms shrink fast enough for the total to converge to a/(1−r). Stating the condition |r| < 1 is part of the answer, and frequently a mark on its own.

Vectors in Two Dimensions →

What's the difference between a position vector and a displacement vector?
A position vector locates a point relative to the origin O (OA = a). A displacement vector connects two points: AB = b − a. The 'destination minus start' rule for AB is the single most useful fact in the topic.
How do I find a unit vector?
Divide the vector by its own magnitude: v/|v|. For 3i − 4j the magnitude is 5, so the unit vector is (3i − 4j)/5. A unit vector in a given direction scaled by a speed gives a velocity vector, the standard exam construction.
How do relative velocity questions work?
Position at time t = initial position + t × velocity. For interception, set the two position expressions equal; for closest approach or 'same position' checks, work with the relative position vector. Writing r(t) = r₀ + tv for each ship/plane first turns the word problem into algebra.

Calculus →

How much of the 0606 exam is calculus?
It's the largest single topic and appears on both papers every session, directly and inside applied questions. Across a typical session, calculus-dependent marks commonly reach 25–35 of the 160 total. It is the highest-return topic to master.
What's the difference between dy/dx and d²y/dx²?
dy/dx is the gradient function, the rate of change of y. d²y/dx² differentiates again: the rate of change of the gradient, used to classify stationary points (negative → maximum, positive → minimum).
Do I need radians for calculus with trig functions?
Yes. The derivatives sin x → cos x and cos x → −sin x are only true in radians. Any calculus question involving trig assumes radian measure throughout.

Revision & study habits

How to Memorise Add Math Formulae and Identities (So They Stay) →

How long does it take to memorise the full 0606 formula list?
With two 10-minute blank-page drills per week plus normal question practice, most students have the list secure in 3–4 weeks, and crucially, it stays secure because the drills continue.
Should I memorise or derive trig identities?
Both: memorise the core three (tan = sin/cos, sin² + cos² = 1, and the reciprocal definitions) and *derive* the sec²/cosec² forms by dividing through, knowing the derivation means a memory blank costs ten seconds, not the question.

Building Speed for the Non-Calculator Paper →

How long does it take to get fast at non-calculator work?
Visible change in about three weeks of daily 10-minute drills; comfortable Paper 1 speed in six to eight. The skill responds to frequency more than duration, daily beats weekly at the same total minutes.
Is it normal to be slow at mental maths after years of calculator use?
Completely. Most IGCSE students have outsourced arithmetic since primary school. The speed comes back with use, it is rebuilding, not building, and rebuilding is faster.

How to Revise IGCSE Add Math (a Method, Not a Mood) →

Why doesn't re-reading notes work for Add Math?
Because 0606 is examined by doing, not recognising. Re-reading creates familiarity that feels like knowledge but collapses under a blank page and a timer. Every effective Add Math revision activity involves writing solutions.
How early should I start revising for 0606?
Light, continuous revision (weekly re-dos of failed questions) should run all year. Dedicated exam revision works well from 8–10 weeks out, enough for full topic coverage plus a proper past-paper phase.

How to Show Working and Stop Losing Method Marks →

How many marks does bad working actually cost?
From marked scripts we see weekly: a typical capable student with mental-maths habits donates 10–15% of the paper, one to two grades, to invisible working. It is the largest single fixable loss in 0606.
Won't writing everything slow me down too much?
Full working costs roughly 10–15 seconds per question part and routinely saves multiple marks. After two weeks of practising the habits they run at full speed, the trade is overwhelmingly positive.

Managing IGCSE Exam Stress (Without Pretending It Away) →

Is exam anxiety normal before Add Math?
Very. Add Math's single-tier papers and the non-calculator change make it a focal point for IGCSE stress. Moderate nerves actually sharpen performance; the goal is keeping anxiety in the useful range, mainly through preparation that removes genuine unknowns.
What helps most in the final week?
Sleep, light familiar practice, and stopping on time. The final week consolidates what exists; it cannot build new capability, and all-nighters trade real accuracy for imagined coverage.

The question behind all the questions

“Will this work for my child?” That one needs a class, not a paragraph. The free 1-hour trial answers it properly, and it costs you exactly nothing.
