IGCSE Mathematics one-month revision plan 2026: A complete week-by-week guide
One month is a tight window, but it is a powerful one if you use it correctly. A structured IGCSE Mathematics one month revision plan does not mean reading through your notes again. It means targeted, high-intensity practice that forces your brain to retrieve information under pressure, identify weaknesses before the examiner does, and build the stamina to sustain concentration across a two-hour paper.
This guide lays out exactly how to approach every week of your 30 day revision IGCSE schedule, which topics to attack first, how many past papers to complete, and what to do in the final 72 hours before you walk into the exam hall.

How to assess your starting point before beginning your IGCSE Maths revision
Before you open a single textbook, you need an honest snapshot of where you currently stand. Drawing on years of experience at Times Edu, one of the most common errors students make is beginning revision without a clear diagnostic baseline, which means they spend time reinforcing what they already know and avoid the topics that are costing them marks.
Run a timed diagnostic paper first. Take one Cambridge 0580 [1] past paper from the last two years and complete it under exam conditions, without notes and with a timer running. Score it against the official mark scheme and sort your errors into two categories: Topics you have never been taught or have forgotten completely, and careless slips on content you actually understand.
This single step transforms your IGCSE Maths revision plan from generic to personalised. Once you have your diagnostic score, you can allocate more revision days to your weakest syllabus sections and compress time on topics where you are already performing at the B or A boundary.
| Diagnostic score range | Likely grade boundary | Priority action |
|---|---|---|
| Below 40% | Grade D or below | Focus weeks 1 and 2 entirely on core concept gaps |
| 40–59% | Grade C to B | Balance concept review with past paper output |
| 60–74% | Grade B to A | Shift quickly to exam technique and mark scheme fluency |
| 75% and above | Grade A to A* | Prioritise speed, error elimination, and hard Extended questions |

Week one: Consolidating number, algebra and functions in IGCSE Mathematics
The first week of your IGCSE Maths four week plan should be dedicated to the highest-yield topics on the Cambridge 0580 specification. Algebra and number together account for a significant proportion of the total marks available, which makes them the most logical starting point for any student targeting a grade improvement.
Days 1 to 3: Algebra and equations. Work through changing the subject of a formula, expanding and factorising quadratics, solving simultaneous equations algebraically and graphically, and manipulating algebraic fractions. A common mistake we see at Times Edu is students who can factorise simple quadratics but freeze when the coefficient of x² is not 1. Practise non-monic quadratics until this feels automatic.
On each of these days, complete at least 20 topical questions from a structured question bank such as Physics and Maths Tutor. Do not skip showing full working, because Cambridge awards method marks even when the final answer is wrong.
Days 4 to 5: Functions. Composite functions written as fg(x), inverse functions written as f⁻¹(x), and domain and range restrictions appear consistently in the Extended tier. One critical detail often overlooked is that students apply the functions in the wrong order when computing fg(x), applying f first instead of g. Write the order explicitly in your working every single time until the habit is locked in.
Days 6 to 7: Vectors. Geometric vector proofs require you to express paths in terms of given vectors and then demonstrate collinearity or parallelism. Draw every vector diagram by hand, label the paths, and write the algebraic proof alongside the diagram. If you cannot see the geometry, you cannot write the algebra.

Week two: Geometry, mensuration and trigonometry in IGCSE Mathematics
Geometry is one of the most mark-dense sections of the Cambridge 0580 revision schedule. Students who invest time here typically see some of the sharpest grade improvements because many geometry questions have predictable structures and require learned reasoning patterns rather than creative problem-solving.
Days 8 to 10: Circle theorems and geometric reasoning. There are eight circle theorems that Cambridge tests, and the mark scheme demands specific phrasing when you state a reason. Memorise phrases such as “angles in the same segment are equal” and “opposite angles of a cyclic quadrilateral sum to 180 degrees.” Writing a correct angle value without the correct reason costs you the second mark on every such question.
In our experience working with international students, circle theorems are the single most common source of avoidable mark loss in the geometry section. Students get the number right but write a vague or incorrect reason and lose a mark they should have earned.
Days 11 to 12: Trigonometry and Pythagoras. Review SOH CAH TOA for right-angled triangles, then move into the Sine Rule and Cosine Rule for non-right-angled triangles. Cambridge 0580 frequently embeds trigonometry inside 3D problems where you must first identify the correct 2D triangle before applying any formula. Sketching the 3D shape and isolating the relevant face is a technique worth practising repeatedly.
Days 13 to 14: Mensuration. Surface area and volume questions for spheres, cones, cylinders, and compound shapes appear in almost every Paper 4. Know the formulas from memory, but also know when a question asks for the curved surface area only versus the total surface area, because confusing these is a frequent source of full question loss even among stronger students.
| Geometry topic | Mark weight | Common error |
|---|---|---|
| Circle theorems | High | Correct angle, missing or wrong reason |
| Trigonometry (non-right-angled) | High | Applying Sine Rule when Cosine Rule is needed |
| 3D trigonometry | Medium-High | Failing to identify the correct 2D triangle |
| Mensuration | High | Confusing curved surface area with total surface area |
| Transformations | Medium | Incorrect centre of rotation or wrong vector for translation |

Week three: Statistics, probability and graphs in IGCSE Mathematics
By the time you reach week three of your week by week IGCSE Maths plan, you should have covered the bulk of the pure mathematics content. This week shifts focus to statistics, probability, and the various graph types that Cambridge tests across both papers.
Days 15 to 17: Probability. Probability trees for dependent events, where outcomes are selected without replacement, consistently appear in Paper 4 and carry multiple marks. The key discipline here is updating the denominator after each selection. Students who write the same denominator for both branches of the second tier lose marks on almost every question of this type.
Conditional probability expressed using correct notation is also testable at the Extended level. Practise reading probability from two-way tables, Venn diagrams, and tree diagrams so that you are not thrown by the format in which the information is presented.
Days 18 to 19: Statistics and cumulative frequency. You need to be confident constructing cumulative frequency curves, reading the median and quartiles from them, and interpreting box-and-whisker plots. A common mistake we see in this section is students who plot points at the midpoint of each class interval rather than the upper class boundary, which produces an entirely incorrect curve.
Histograms with frequency density on the vertical axis are another reliable Cambridge staple. Practise the calculation in both directions: Computing frequency density from the table, and reading frequency from a given histogram.
Days 20 to 21: Graphs and functions. Sketch and interpret straight-line graphs, quadratic curves, cubic curves, reciprocal graphs, and exponential functions. For distance-time and speed-time graphs, know how to calculate average speed from a distance-time graph and acceleration from a speed-time graph. Drawing a tangent to a curve to estimate gradient is a technique that requires physical practice with a ruler.

Week four: Full past papers, mark scheme analysis and final weak spots
The final week of your IGCSE Mathematics one month revision plan is where the real grade gains are consolidated. This is not the week to learn new content. It is the week to convert your understanding into consistent marks under exam conditions.
Days 22 to 25: Timed past papers under strict conditions. Complete one full Cambridge 0580 paper every day. Set a timer for ten minutes less than the official paper duration to build a speed buffer and ensure you are never racing against the clock in the real exam. No notes, no phone, and no music.
After each paper, spend at least 30 minutes scoring it using the official Cambridge mark scheme. Log every dropped mark in a notebook with two columns labelled “concept gap” and “silly mistake.” This distinction matters because concept gaps require re-learning, while silly mistakes require a different fix: A personal checklist of the specific errors you repeat.
Days 26 to 27: Revisiting logged errors and Non-Calculator skills. Go back through your error log and redo every question you dropped marks on across the previous five days. If your exam includes a non-calculator paper (Cambridge 0580 Paper 1 and Paper 2), this is the moment to drill long division, fraction arithmetic, and surd simplification entirely by hand.
One critical detail often overlooked is calculator mode. Verify that your calculator is set to Degree mode before every paper. Students who work through an entire trigonometry section in Radian mode produce answers that score zero, even with perfect method.
Days 28 to 30: Error cleansing, toolkit check, and rest. On Day 28, do not start a new paper. Review your full Silly Mistakes log from the entire month and redo every single question in it. This consolidates the corrections into long-term memory rather than short-term awareness.
On Day 29, check your physical exam kit: Geometric compass, protractor, clear plastic ruler, sharp HB pencils, black ink pens, and your approved calculator. Review the standard rounding guideline: Three significant figures for numerical values unless the question specifies otherwise, and one decimal place for angles.
On Day 30, close your books by 2:00 PM. Sleep early. Your brain processes and consolidates the month’s learning during deep sleep, and arriving cognitively fresh is worth more than a final cramming session.

Daily revision routine and resources to support your IGCSE Maths one-month plan
A revision timetable IGCSE students can actually follow is one that respects cognitive limits. Four to five hours of focused daily revision with structured breaks produces better results than eight hours of unfocused reading, particularly in the lead-up to high-stakes exams.
Recommended daily structure:
- Morning session (90 minutes): New topic study or topical practice questions
- Break (20 minutes): Physical movement, not screen time
- Afternoon session (90 minutes): Past paper questions or exam simulations
- Evening review (30 minutes): Update your error log, review mark scheme phrasing, plan the next day
Recommended resources for this revision routine Cambridge Maths students should keep on hand:
- Cambridge 0580 past papers and mark schemes: Available free from the Cambridge International website
- Physics and Maths Tutor: Topical question banks sorted by Cambridge syllabus section
- Cognito or SaveMyExams video explanations: For quick concept clarification on topics you have forgotten
- A physical squared-paper notebook: For working through problems by hand, not on screen
Drawing on years of experience at Times Edu supporting students across IGCSE, A Level, and IB programmes, the students who improve most sharply in a one-month window are those who treat their error log as seriously as the past papers themselves.
