Who It Is For

Who IGCSE mathematics tutoring is for

Typically students in Year 10 and Year 11, or their international equivalents, working towards a Cambridge or Edexcel IGCSE mathematics entry.

Students moving onto Extended tier

Where the step up from Core to Extended has exposed gaps in algebra, and confidence has dipped as a result.

Students targeting grade 8, 9 or A*

The final grade boundaries are won on precision and pacing, not on content the student has never met. That is a different kind of preparation.

Students new to the IGCSE system

Families who have moved school or country mid-course and need the gap between the old curriculum and the IGCSE specification mapped and closed.

Students who freeze in timed papers

Where the mathematics is understood in lessons but falls apart under exam conditions, which is a technique and pacing problem rather than a knowledge one.

Students preparing to continue to A Level

IGCSE algebra is the foundation the whole of A Level Pure rests on. Weak algebra at 16 becomes a much larger problem at 17.

Students resitting

Where a previous sitting fell short and the priority is identifying exactly which marks were missed and why, rather than repeating the whole course.

The Course

What IGCSE mathematics actually covers

IGCSE mathematics is a two-year course that takes the arithmetic and early algebra of lower secondary and turns it into a working toolkit: manipulating expressions rather than just evaluating them, reasoning about shapes rather than just measuring them, and handling data rather than just reading it off a chart. The content is broad rather than deep — there are a lot of separate techniques, and most questions use two or three of them together.

The step that catches students out is not the difficulty of any individual topic. It is that the course stops telling you which technique to use. In lower secondary, a question about Pythagoras appears in the chapter on Pythagoras. On an IGCSE paper it appears inside a question about a ladder, a bearing or a cone, and the student has to recognise it. That shift — from knowing the method to knowing when the method applies — is the single biggest source of lost marks at this level.

The other structural feature worth understanding is that a large share of the marks are method marks. They are awarded for identifiable steps of working, not for the final number. A student who does the mathematics correctly in their head and writes only an answer can lose most of the marks on a question they fully understood.

Syllabuses taught: Cambridge IGCSE Mathematics 0580, Cambridge IGCSE International Mathematics 0607 and Pearson Edexcel International GCSE Mathematics A 4MA1. Topic overlap is large; question style and paper structure differ.
Core and Extended: Cambridge entries are made at Core or Extended tier. Extended carries the higher grades and is the route most students need for A Level mathematics; Core caps the available grade range.
Assumed on entry: Fluency with fractions, negative numbers, and substituting into a formula. Where these are shaky the diagnostic finds it, because almost every later topic rests on them.
What it leads to: A Level or AS mathematics, and IB. Algebraic fluency built here is what makes the transition manageable — A Level assumes it rather than teaching it again.

Specifications are revised periodically. Always confirm the exact syllabus code and tier your child is entered for with their school, and lessons will be matched to it.

What Usually Goes Wrong

Where IGCSE mathematics marks are usually lost

The examiner reports repeat the same themes year after year. These are the patterns that come up most in diagnostic sessions.

Where the marks go

Algebraic manipulation that is nearly right — a sign error in an expansion, a dropped denominator in a rearrangement.
Working done mentally or on a calculator, so method marks cannot be awarded.
Circle theorems and geometric reasoning stated as answers without the required justification.
Bearings, similar shapes and compound measures misread because the diagram was never annotated.
Cumulative frequency, histograms and box plots half-learned, so easy marks are dropped late in the paper.
Paper 2 running out of time because the early questions were done too carefully.

What we do about it

Algebra rebuilt to fluency first, because almost every other topic on the paper depends on it.
Full written solutions modelled live, then compared line by line against the published mark scheme.
Geometric reasoning practised as written justification, in the phrasing the mark scheme accepts.
A standard annotation routine for every diagram question, applied until it is automatic.
Statistics and data handling drilled as a scoring opportunity rather than an afterthought.
Timed papers with a per-question time budget, so pacing is rehearsed rather than hoped for.

Most IGCSE candidates who miss their target grade do not have a knowledge problem across the whole syllabus. They have three or four specific technique problems that recur on every paper.

Conceptual Mistakes

The conceptual mistakes that repeat every year

These are not gaps in knowledge. In every case below the student can already do the mathematics — what is missing is knowing when it applies, or what the examiner is actually asking for.

“Solving an equation and finding where a graph crosses the axis are different topics”

What the student believes

Solving x² − 5x + 6 = 0 is an algebra question. Finding where the curve y = x² − 5x + 6 meets the x-axis is a graphs question, and feels like something separate that has not been covered.

What is actually true

They are the same question. Every point on the x-axis has y = 0, so “where does the curve meet the x-axis” means exactly “solve the equation with y set to 0”. The student already has the method; nobody has told them the two phrasings point at it.

How it is taught By collecting the phrasings that all mean “set it equal to zero” — roots, zeros, solutions, x-intercepts, where the curve cuts the axis — and drilling the translation until the trigger is automatic.

“A 20% increase is undone by a 20% decrease”

What the student believes

If a price went up by 20% to reach $60, then taking 20% off $60 gets back to the original. So the answer is 60 × 0.8 = $48.

What is actually true

The two percentages are taken of different amounts. The increase was 20% of the original; the decrease would be 20% of the new price. The original satisfies original × 1.2 = 60, so it is 60 ÷ 1.2 = $50 — and 50 × 1.2 checks back to 60 exactly.

How it is taught By making the student write the multiplier equation before touching the numbers, and by always substituting the answer back. Reverse percentage is one of the most reliably examined topics on the paper and one of the most reliably lost.

“If the answer is right, the marks are right”

What the student believes

Working is something you show if you feel like it. The examiner is checking whether the final number is correct.

What is actually true

On IGCSE papers most multi-step questions carry method marks, awarded for identifiable steps regardless of whether the final value comes out right. A student who works mentally and writes one line can score 1 out of 4 on a question they understood completely — and a student who makes an arithmetic slip but shows every step can still score 3.

How it is taught By marking the student’s own work against the published mark scheme with them, so they see where the marks physically sit. It changes how they write every answer afterwards.

“Round as you go, it makes the numbers easier”

What the student believes

Rounding an intermediate value to 2 decimal places keeps the working tidy and cannot change much.

What is actually true

It compounds. In a multi-step trigonometry or compound-interest question, rounding at each stage can move the final answer outside the accepted range, and the accuracy mark is lost even though every method mark was earned. Full calculator accuracy is carried through and rounded once, at the end.

How it is taught By teaching the calculator’s answer-recall and memory functions properly, so carrying the exact value forward is easier than rounding it.

Exam Technique

The exam technique problems specific to IGCSE papers

Separate from the mathematics, and separately teachable.

Command words change what is required

“Work out” wants a value. “Show that” gives you the answer already and awards marks only for the reasoning that reaches it — writing the answer down scores nothing. “Give an exact answer” forbids a decimal. Students who read past these lose marks they had earned.

The default accuracy rule

Unless told otherwise, non-exact answers are given to three significant figures, and angles usually to one decimal place. This is a rule about presentation, not mathematics, and it costs marks on papers where every method step was correct.

Knowing what is on the formula list

Some formulae are provided and some are assumed. Time spent memorising what is printed for you is wasted; time not spent memorising what is not printed is expensive. The diagnostic establishes which list applies to the entered specification.

Question selection and pacing

Marks are not distributed evenly by difficulty. Spending twelve minutes rescuing a four-mark question while eighteen accessible marks sit unattempted at the back of the paper is the most common way a capable student underperforms.

Answering the question that was asked

A question asking for the perimeter after a long area calculation, or for the value of y after solving for x, is a standard structure. The final line of the question is worth re-reading before writing the final line of the answer.

Structured questions build on themselves

In part (b) you are usually expected to use the result from part (a). Students who restart from scratch lose time; students who spot the dependency often find (b) is two lines long.

The Learn with Tahira Method

How IGCSE preparation is structured

The same six stages run behind every pathway. Every lost mark is classified as knowledge, method, arithmetic or time, and the teaching that follows is chosen to match the cause that dominates. Here is what the stages that matter most contain for this specification.

Diagnose
Rebuild
Recognise
Write
Rehearse
Refine

Diagnose

Diagnose against the specification

The free assessment maps what the student can do onto the actual syllabus content list, so the plan targets named topics rather than a general impression.

Rebuild

Rebuild algebra first

Indices, expansion, factorisation, rearrangement and simultaneous equations come before anything else, because the rest of the paper leans on them.

Recognise

Drill topic by topic with past questions

Each topic is closed with topical past-paper questions from real Cambridge and Edexcel papers until the method is reliable, not merely familiar.

Rehearse

Move to full timed papers

Once coverage is secure, complete papers under exam conditions, marked against the official scheme so the student sees precisely where marks were and were not earned.

After every mock the audit is re-run, so the next block of lessons follows whichever cause is now costing the most marks.

Example Problem Types

Three problems that show where the marks actually go

Worked through the way they are taught in a session — including the reasoning that decides which method to reach for.

Reverse percentage: the multiplier is the whole method

After a 20% increase, a jacket costs $60. Work out the original price.

The common error Taking 20% off the new price: 60 × 0.8 = $48. This is wrong because the 20% was a percentage of the original, not of $60.

Working

Write what the increase did as a multiplier: original × 1.2 = 60.
The unknown is being multiplied by 1.2, so divide: original = 60 ÷ 1.2.
original = $50.
Check by going forwards: 50 × 1.2 = 60. ✓

The point The mathematics here is one division. What makes it hard is recognising that the question runs the process backwards, which is signalled by the price being given after the change. Students who write the multiplier equation first get this right every time; students who reach for a percentage of the number in front of them get it wrong every time.

Quadratics: the same method, hidden behind different words

The curve y = x² − 5x + 6 meets the x-axis at two points. Write down their coordinates.

The common error Treating this as a graph-sketching question and attempting to plot points, or leaving it blank because “we have not done this kind”.

Working

Every point on the x-axis has y = 0. So substitute: x² − 5x + 6 = 0.
Factorise. Two numbers multiplying to +6 and adding to −5 are −2 and −3: (x − 2)(x − 3) = 0.
A product is zero only if a factor is zero, so x = 2 or x = 3.
The question asked for coordinates, not values of x: (2, 0) and (3, 0).

The point Nothing here is beyond a student who can factorise — and almost every IGCSE student can factorise. The mark is won or lost at step 1, in recognising that “meets the x-axis” is instruction to set y = 0. Note also step 4: the question asked for coordinates, and answering “2 and 3” would drop the final mark.

Circle theorems: one word tells you which theorem

AB is a diameter of a circle. C is a point on the circumference. Angle CAB = 34°. Work out angle ABC.

The common error Searching through every circle theorem in turn, or assuming the triangle is isosceles because two sides look similar in the diagram.

Working

The word diameter, with a third point on the circumference, is the trigger for the angle in a semicircle. So angle ACB = 90°.
ACB is now a triangle with two known angles.
Angles in a triangle sum to 180°: angle ABC = 180 − 90 − 34.
angle ABC = 56°.

The point Circle theorem questions are usually short once the right theorem is identified, and unanswerable until it is. The teachable skill is not the theorems themselves — students can recite those — but the features that trigger each one: a diameter, a tangent, a cyclic quadrilateral, two radii. Lessons drill the triggers, not the recitation.

Revision Strategy

How to revise IGCSE mathematics so the marks actually move

Re-reading notes and re-watching worked solutions feels productive and changes very little. This is the sequence used between sessions.

1

Start from the specification, not the textbook

Print the syllabus content list for the entered code and mark each item green, amber or red honestly. Revision aimed at a list is finite and checkable; revision aimed at “maths” is neither. The diagnostic produces this list for you.
2

Revise by doing questions, not by reading

The exam asks you to produce solutions under time pressure, so practice has to be production, not recognition. Reading a worked solution and understanding it is not evidence you can generate it — that gap is exactly what surprises students in the hall.
3

Work in topical sets while coverage is still weak

Questions grouped by syllabus area let you attack one weakness at a time and see improvement within a session. Full mixed papers at this stage mostly demonstrate that the gaps still exist.
4

Redo the questions you got wrong, a week later

Marking a question and reading the correct method closes the loop far less than reattempting it cold after a delay. If it cannot be reproduced a week on, it was never learned.
5

Keep a short error log, sorted by cause

For each lost mark write one line: was it knowledge, method choice, arithmetic or time? After two weeks the dominant cause is obvious, and revision can aim at it rather than at everything.
6

Switch to timed full papers once red topics are cleared

Timed papers train pace and question selection, which cannot be trained any other way. Starting them before coverage is secure produces demoralising scores that measure the gaps rather than the technique.

Past Papers

Using IGCSE past papers properly

Past papers are the most valuable revision resource available and the most commonly misused. Working through twenty of them without changing anything in between produces twenty similar scores.

Topical first, full papers later

Questions grouped by syllabus area target a named weakness. Full papers are for rehearsing pace and selection once coverage is broadly secure. Doing them in the wrong order wastes the papers, of which there is a finite supply.

Mark against the official scheme, not the answer

The mark scheme shows where the method marks sit and what wording is required. Reading it is how a student learns what “enough working” actually means — and it is written for teachers, so the first few need to be read together.

Match the paper to the specification

A Cambridge 0580 paper is not practice for Edexcel 4MA1 and vice versa. The topic overlap tempts students to use whatever they find; the question phrasing and paper structure differ enough to matter.

Read the examiner reports

Boards publish reports describing what candidates actually did wrong that session. They are the closest thing to being told the answer in advance, and almost no student reads them.

Save recent papers for the end

The most recent two or three series are the best predictors of current question style. Burning them in October leaves nothing realistic for the final rehearsal in April.

Timing data is data

Record where the time actually went, not just the score. A student consistently losing eight marks at the back of the paper has a pacing problem, and no amount of extra topic revision will fix it.

Topical past-paper compilations, mark schemes and worked solutions are supplied as part of the tutoring — there is nothing to buy.

Measuring Progress

How IGCSE progress is measured

Against the written roadmap produced after the diagnostic, so there is a fixed reference point rather than a general impression of how lessons are going.

Session by session

The practice set is reviewed, not marked

Each lesson opens by working through the previous week’s set to find where the reasoning broke, which is where the next gap usually surfaces.

End of each topic

A short syllabus-area assessment

A focused set of past-paper questions on the area just covered. The topic moves from red to amber to green on the roadmap only when it is reproduced cold, not when it was understood in the lesson.

Every two weeks

A written report to parents

Topic mastery against the roadmap, any mock timings, and what has been adjusted. Specific enough that you can tell whether it is working without having to ask.

Final term

Timed papers with a cause breakdown

Each full paper is marked against the official scheme and every lost mark classified as knowledge, method, arithmetic or time. The next block of lessons follows whichever cause dominates.

Throughout

Recorded lessons stay available

Every session is archived, so a circle theorem argument or a histogram method can be replayed the night before the paper.

Any time

A straight answer on request

If a target grade stops being realistic in the time remaining, you are told at the point it becomes clear rather than in results week.

How Sessions Work

How IGCSE sessions run

Format: Live one-to-one on Zoom, 60 minutes, with a pen-tablet driving a shared whiteboard so every step of a solution is written out as it is explained.
Frequency: Usually one weekly session through the year, increasing in the final term as timed papers are added. The diagnostic gives a specific recommendation.
Between sessions: A targeted practice set matched to the topic just covered. Solutions are reviewed together at the start of the next lesson rather than simply marked.
Materials: Topical past-paper compilations, mark schemes and worked examples are supplied. There is nothing to buy.
Progress checks: A short topic assessment at the end of each syllabus area, and full papers once coverage is complete.
Starting point: A free 40-minute diagnostic, then a written roadmap within 24 hours. You decide after reading it.

Questions Parents Ask

IGCSE mathematics tutoring questions

Which IGCSE mathematics syllabuses do you tutor?

Cambridge IGCSE Mathematics (0580), Cambridge IGCSE International Mathematics (0607) and Pearson Edexcel International GCSE Mathematics A (4MA1). The topic overlap between them is large, but the paper structure and the way questions are phrased differ, and lessons are matched to the specification the student is actually entered for.

Should my child take Core or Extended tier?

Extended is required for a grade above C/5 and for most A Level mathematics entry, so it is the right target for anyone continuing with the subject. The honest answer for a specific student depends on where they are now and how long remains, which is exactly what the diagnostic session establishes.

My child gets the right answers but still loses marks. Why?

On IGCSE papers a large share of the marks are method marks, awarded for identifiable steps rather than the final value. Students who work mentally or skip lines forfeit them even when the answer is correct. Lessons address this directly by writing full solutions out and comparing them against the published mark scheme.

Do you use past papers?

Yes, and they are the backbone of the preparation. Practice starts with topical question sets grouped by syllabus area so a specific weakness can be drilled, and moves to full timed papers once the topic coverage is secure.

How long before the exam should IGCSE tutoring start?

Starting at the beginning of the final year gives room to rebuild foundations properly and still leave a full term for timed practice. Later than that is workable, but the plan shifts towards securing the marks that are most reachable rather than covering everything.

Is the tutoring available outside the UK?

Yes. IGCSE is an international qualification and the lessons are online, scheduled around the student’s time zone. There are regular slots for families in the UAE, the USA and elsewhere.
