What Equipment Do You Need for a GCSE Maths Exam?

The Core Checklist

• Black ballpoint pens, at least two, for written answers
• Pencils for diagrams, graphs and constructions
• A rubber (eraser)
• A ruler, ideally 30cm, for graphs, constructions and accurate diagrams
• A protractor for angle questions
• A pair of compasses for constructions and loci
• A scientific calculator for the calculator paper
• A clear pencil case, plus spares of the small items

Most centres allow a small transparent bag or clear pencil case instead of a formal one, but check what your school prefers. The clear case is not just convention: it lets invigilators see contents quickly, which means fewer questions on your way in.

The Calculator Rules in Plain English

Under JCQ rules, you may use a calculator in an exam unless the paper or the awarding body's specification says otherwise, and the front of each GCSE Maths paper states which papers allow one. You are responsible for making sure your calculator meets the rules, and there is no official list of permitted models.

• It must be a device whose primary purpose is mathematical calculation, so phones and smartwatches never qualify
• It must not have language translation, symbolic algebra manipulation or symbolic calculus functions
• Clear anything stored in its memory and make sure it is in exam mode where the model has one
• Remove lids, cases or covers with printed instructions or formulae
• Do not bring operating instructions or prepared programs into the exam room
• Check the batteries are working properly before the exam
• Do not borrow a calculator from another candidate during the exam; an invigilator may supply a replacement if yours fails

A standard UK school scientific calculator, such as the Casio fx-83 or fx-85 range, is compliant out of the box. If you want help choosing, our guide to which calculator to use for GCSE Maths covers the practical options and what the rules mean for them.

Spares and Condition

Pens run out at the worst moments, and a pencil with no lead is not equipment. Take two black pens, two pencils and a spare battery if your calculator uses replaceable ones, or a fully charged calculator if it is rechargeable. Check everything days before the exam, not the morning of it, and use the same calculator in every practice paper so its buttons are automatic by exam day.

Equipment failure during the paper is survivable, as our guide to what happens if your calculator stops working in a GCSE Maths exam explains, but a spare or a well-checked battery removes the risk almost entirely.

What Not to Bring

• Mobile phones, smartwatches or any internet-connected device
• Notes, revision cards, formula sheets or calculator instruction booklets
• Calculator cases or lids with printed formulae on them
• Correction fluid, unless your centre permits it; crossing out is always safe
• Food packaging with printed text, in many centres

JCQ's warning to candidates is blunt: bringing prohibited material into the exam room is a breach of the rules even if you never use it. If in doubt, leave it in your bag outside the room, and ask an invigilator before the exam starts rather than after.

Follow Your Own Centre's Instructions

Everything above is the general picture. Your school or exam centre issues its own exam instructions, including timings, where to leave bags and any local rules about pencil cases, water bottles or what may be on your desk. Those instructions override general guidance, so read them when they arrive and ask your exams officer if anything is unclear.

A calm final evening routine also does more for your marks than any last-minute cram. Our guide to the night before a GCSE Maths exam covers packing your equipment, checking your calculator and getting properly prepared without stress.

Equipment Is the Easy Part

A complete pencil case takes one shopping trip and five minutes of checking. Knowing what to do with the equipment takes longer, so give that the real preparation time: practise with your calculator until its habits are automatic, because calculator mistakes are one of the cheapest ways to lose marks, and read up on the GCSE Maths exam format so nothing in the paper surprises you.
