GCSE Maths is the only subject most pupils have to retake until they pass at grade 4 — which is exactly why the pressure feels so high. The good news: the syllabus is finite, the exam style is predictable, and consistent practice reliably moves grades up. Here's the playbook.
Foundation tier vs higher tier
Foundation tier covers grades 1–5. Higher tier covers grades 4–9. You sit one or the other, not both. Foundation is appropriate if you're confidently aiming for a 4 or 5; higher is essential if you want a grade 7, 8 or 9 (no foundation paper can award above a 5).
The six syllabus areas (AQA, Edexcel, OCR — all the same)
- Number — fractions, decimals, percentages, standard form, surds.
- Algebra — linear and quadratic equations, sequences, simultaneous equations, graphs.
- Ratio, proportion and rates of change — direct and inverse proportion, growth, compound interest.
- Geometry and measures — angle rules, Pythagoras, trigonometry, area, volume.
- Probability — tree diagrams, mutually exclusive events, conditional probability.
- Statistics — averages, scatter graphs, cumulative frequency, box plots.
Higher tier topics that gatekeep grade 7+
If you can't do these confidently, grade 7 is out of reach: completing the square, the quadratic formula, algebraic fractions, vectors, circle theorems, sine and cosine rule, and proof by counter-example. Drill these specifically before broader revision.
The exam structure
Three papers, each 1 hour 30 minutes, each worth 80 marks. Paper 1 is non-calculator; Papers 2 and 3 are calculator. The total is 240 marks, scaled to determine your grade.
Exam technique that wins marks
- Show your method — most questions award method marks even if your final answer is wrong.
- Don't leave blanks — try something. Wrong attempts often pick up a mark; blanks always score zero.
- Underline what's asked — many marks are lost answering the wrong question.
- Check units — answers in cm² when the question asked m² lose all the marks.
- Round only at the end — premature rounding loses accuracy marks.
A 12-week revision plan
Weeks 1–4: topic-by-topic, work through your weakest areas first. 30 minutes a day is plenty.
Weeks 5–8: alternate topic drills with full past papers. Mark them yourself with the official mark scheme — examiner thinking is a skill in itself.
Weeks 9–11: full past papers under exam conditions. Aim for 2 a week minimum. Treat your error log (questions you got wrong) as your most valuable revision resource.
Week 12: taper. Light revision, plenty of sleep, no all-nighters.
How long should I revise per day?
Steady wins. 45–60 minutes a day for 3 months beats 6 hours a day for 2 weeks every time. Your brain needs sleep to consolidate — overnight gaps are part of the learning, not a break from it.

Start mock test 1Quick study plan
If you only have a fortnight to prepare, split your time into three blocks. Spend the first few days reading any official handbook or syllabus straight through — don't try to memorise yet, the goal is familiarity. Move on to topic-by-topic revision, focusing on the areas you found least intuitive on the first read. In the final week, switch to timed mock tests under exam conditions; mark every paper ruthlessly and read every explanation, including for questions you got right by guessing. Most candidates improve by 8–12 marks between their first and third mock simply by closing knowledge gaps this way.
Common myths to ignore
Three myths trip up more candidates than any single topic. The first is that "if I sit enough mocks, I'll spot the real questions on test day" — modern UK exam banks contain hundreds of items and the question you see on the day will probably be brand new to you. The second is that you can cram the night before; most assessments reward calm focus more than recent recall, and tired candidates make basic mistakes. The third is that the pass mark is the only thing that matters: aiming for a comfortable buffer of 5–10 marks above the threshold is the single best insurance against an unlucky paper.
What to do on test day
Plan to arrive 15–20 minutes early with valid photo ID — usually a UK driving licence or passport — and any booking confirmation you've been emailed. Eat something light beforehand, drink water but not so much that you'll need a comfort break mid-paper, and silence your phone before you walk through the door. Read every question twice, flag anything you're unsure of, and never leave a blank — there's no negative marking on the assessments most readers of this site sit, so a considered guess is always better than no answer at all.
