The GCSE maths non-calculator paper is Paper 1: at AQA and at Pearson Edexcel, it lasts 1 hour 30 minutes, carries 80 marks and counts for a third of the grade. In summer 2027 it is sat on Friday 14 May, in the morning, almost two weeks before the first calculator paper.
Calculators are allowed only in Papers 2 and 3, so Paper 1 rewards students who can handle fractions, percentages, powers and estimates in their head or with a short written method. This guide covers what the paper tests, the dates of all three papers, the mental methods that save the most time and the habits that protect marks on the day. The facts come from the AQA specification and the Pearson Edexcel timetable; if your school uses another exam board, check its own documents, because paper numbers can differ.
Which GCSE maths paper is the non-calculator one
For AQA and Pearson Edexcel, the answer is the same. In the AQA GCSE Mathematics specification (8300), Paper 1 is non-calculator and Papers 2 and 3 allow a calculator. Pearson Edexcel's GCSE in Mathematics (1MA1) follows the same pattern: Paper 1 without a calculator, Papers 2 and 3 with one.
All three papers share the same format: 1 hour 30 minutes, 80 marks and a third of the final grade each. They are taken at the same tier, Foundation (grades 1 to 5) or Higher (grades 4 to 9), and in the same exam series, so a student cannot sit Paper 1 at Higher tier and the other two at Foundation.
The specification also states that content from any part of the course may be assessed on any paper. Paper 1 is therefore the same maths as the other two, with questions that can be worked without a machine. Expect to calculate exactly with fractions, to leave answers in terms of π and, at Higher tier, to simplify surds such as √12 = 2√3, all of which appear in the specification.
GCSE maths paper 1: what it tests
Paper 1 draws on the whole course. According to the AQA specification, the weighting of each topic area is prescribed by Ofqual and is common to all exam boards; the figures are approximate and apply to the three papers together, not to each one. At Foundation tier, number and ratio account for about 25% of the marks each, algebra for 20%, geometry for 15% and probability and statistics for 15%. At Higher tier, algebra rises to about 30% and number falls to about 15%. Edexcel publishes the same weightings as ranges, for example 22 to 28% for number at Foundation.
Some skills listed in the specification matter more when there is no calculator:
- the four operations with integers, decimals, simple fractions and mixed numbers, including formal written methods;
- calculating exactly with fractions and with multiples of π, and at Higher tier with surds;
- square numbers up to 15 × 15, and knowing that 1,000 = 10³ and 1 million = 10⁶;
- estimating answers and checking calculations by approximation;
- the formulae that are not given in the exam, such as the area of a circle, Pythagoras' theorem and, at Higher tier, the quadratic formula.
AQA's notes add a detail worth remembering on every paper: students should not round values during the intermediate steps of a calculation. Keep fractions, surds and π as they are until the final line, then round only if the question asks for it.
GCSE maths exam dates for summer 2027
GCSE exams are set in common slots agreed by all the boards through the Joint Council for Qualifications, so the maths papers fall on the same days at AQA and at Edexcel. The Pearson Edexcel timetable for summer 2027, published as final, and the provisional AQA timetable give the same three mornings.
| Paper | Calculator | Length and marks | Date in 2027 |
|---|---|---|---|
| Paper 1 | Not allowed | 1 h 30 min, 80 marks | Friday 14 May, morning |
| Paper 2 | Allowed | 1 h 30 min, 80 marks | Thursday 27 May, morning |
| Paper 3 | Allowed | 1 h 30 min, 80 marks | Monday 14 June, morning |
The published start time of a morning session is 9.00am, and schools may move it a little within the boards' rules, so confirm the time with your school. Because the non-calculator paper comes first, the last weeks before 14 May are the moment to sharpen mental methods; the calculator papers follow 13 and 31 days later.
GCSE maths mental methods that save time
Mental methods do not replace written working. They make it shorter, and they catch errors before they cost marks. These six come up across the number, ratio and geometry content of the specification:
| Method | Example | Where it helps |
|---|---|---|
| Find 10%, 5% and 1% first | 15% of 260 = 26 + 13 = 39 | Percentages, interest, VAT |
| Divide by the denominator, then multiply | 3/4 of 84: 84 ÷ 4 = 21, then 21 × 3 = 63 | Fractions of amounts |
| Remove the decimal points, then put them back | 0.3 × 0.4: 3 × 4 = 12, two decimal places, 0.12 | Decimal multiplication |
| Scale both numbers by the same power of 10 | 4.8 ÷ 0.6 = 48 ÷ 6 = 8 | Dividing by a decimal |
| Round to 1 significant figure | 48.7 × 3.12 ÷ 0.49 ≈ 50 × 3 ÷ 0.5 = 300 | Estimates and checks |
| Write numbers as prime factors | 84 = 2² × 3 × 7 | HCF, LCM, simplifying fractions |
The first two rows are one idea: find a simple part, then build the rest from it. Our step-by-step guide to percentages in your head applies it to prices and pay. The estimate in the fifth row lands close to the exact value, about 310, which is all an estimate has to do. The last row depends on recall: when 7 × 12 = 84 is instant, the factor tree almost writes itself, which is why the multiplication tables from 2 to 12 are still worth a few minutes a day at GCSE.
Non-calculator tips for the day of the exam
A few habits protect marks when the arithmetic is all yours:
- Estimate before you calculate. A rough answer in the margin tells you at once if the exact one is ten times too big.
- Write every step. A slip in the arithmetic should not hide a correct method from the examiner.
- Keep values exact. Leave 36π as 36π and 5/12 as 5/12 unless the question asks for a decimal.
- Check with the inverse. If 4.8 ÷ 0.6 = 8, then 8 × 0.6 should give 4.8 back.
- Watch the clock. 90 minutes for 80 marks is just over a minute per mark, and the specification says the demand increases through the paper, so do not let an early question eat ten minutes.
If a question produces a very awkward number halfway through, treat it as a signal to check the previous step. Bring the usual instruments as well: AQA expects a pencil, a ruler, a pair of compasses and a protractor for every paper, including Paper 1.
How to practise between now and May
From early October, a student has more than 30 weeks before Paper 1. Ten minutes of mental arithmetic every day is easier to keep up than a long session once a week, and it keeps the methods fresh. Mix the topics: two percentages, two fractions, one estimate and one power, every day.
Squares up to 15 × 15 extend the times tables. 12 × 12 = 144 is the last line of the 12 times table; 13², 14² and 15², that is 169, 196 and 225, are worth learning by heart, together with the cubes of 2, 3, 4, 5 and 10.
Once a week, take one past non-calculator paper, or half of one, under timed conditions, then mark it and redo every question you dropped. Kalc trains times tables, fractions and percentages in about ten minutes a day, but any routine works if it is regular.
Frequently asked questions
Which GCSE maths paper is non-calculator?
Paper 1, at AQA and at Pearson Edexcel. Papers 2 and 3 allow a calculator. Each paper lasts 1 hour 30 minutes and is marked out of 80.
When is the GCSE maths non-calculator paper in 2027?
On Friday 14 May 2027, in the morning, according to the final Pearson Edexcel timetable and the provisional AQA timetable. Paper 2 follows on Thursday 27 May and Paper 3 on Monday 14 June.
How long is GCSE maths paper 1?
1 hour 30 minutes, for 80 marks. It counts for a third of the GCSE, like each of the two calculator papers.
What formulae do you need to learn for GCSE maths?
AQA lists the formulae that are not given in the exam, including the area and circumference of a circle, Pythagoras' theorem, the area of a trapezium and, at Higher tier, the quadratic formula and the sine and cosine rules. Formulae such as the volume of a sphere or a cone are given in the question.
Can you use a calculator in GCSE maths paper 2?
Yes. Papers 2 and 3 allow a calculator. AQA asks for at least the four operations, square and square root, reciprocal and power functions, brackets, a memory and the usual exponential, trigonometric and statistical functions.
