Most exam-day advice is about your head. This is about the desk. UK exam halls run on a short list of rules almost nobody reads until an invigilator is standing over them, and the consequence is a handful of small decisions you want settled days in advance rather than at eight in the morning with your bag open on the kitchen floor.
Four rules shape the whole kit. Anything on your desk has to be loose or inside a see-through case, because invigilators must see it without touching it. Nothing with a screen that can connect to anything else comes in. Nothing with writing on it comes in, including the label on a drink. And your centre’s own instructions beat anything you read online, this article included — the regulations UK centres work from are published by the Joint Council for Qualifications and are worth ten minutes before study leave ends.
Everything below follows from those four rules. Nothing here is expensive, and most of it you may already own in the wrong form.
1. A Transparent Pencil Case
This is the one item that turns a stressful morning into a non-event, and the one most often wrong. An opaque case means emptying it onto the desk in front of everyone, then writing with your equipment scattered loose where it can roll off.
What matters: genuinely clear rather than tinted, durable enough for a whole exam season in a bag, and small — a large case tempts you to fill it, and an exam hall desk is narrower than the one you revise at. What to ignore: compartments, pen loops and organiser features. You want one transparent volume you can see into at a glance, which is what the invigilator wants too.
Nobody sitting formal exams should skip this. If you would rather not buy anything, a clear food bag is accepted in many centres — ask yours first. Otherwise a basic transparent exam pencil case is the single highest-value purchase on this list.
2. Black Pens, Bought as a Multipack
UK papers are scanned for marking, and scanners handle black ink far better than blue. Many boards require black. Bring three identical pens rather than one good one: a pen failing mid-paper costs minutes you cannot claim back, and the hall has no guaranteed spare.
The feature that matters is drying time, which is the argument for ballpoint over gel on a long written paper. Gel sits wet on the page for a moment — fine until your hand drags across a line you have just written, which left-handed students feel most. Ballpoint is less pleasant to write with and far harder to smudge. Second: make all your pens identical, so your handwriting does not change halfway through.
What to ignore: comfort grips and pressure-sensitivity claims. Three hours of writing is uncomfortable regardless. A plain black ballpoint pen multipack covers every paper you will sit, and the leftovers get used all year.
3. A Pencil, Sharpener and Eraser for Anything Graphical
Graphs, diagrams, labelled sketches, working you may want to change — all better in pencil than in a crossed-out mess of ink. Bring two pencils and a sharpener with a closed barrel that catches shavings, so you are not brushing them off a desk mid-paper.
Hardness matters, and medium is right for exam use: soft grades smudge, hard grades leave lines a scanner struggles with. An eraser that lifts cleanly without shredding matters more than it sounds, because a torn answer booklet is a real problem. Students sitting essay-only papers can carry one pencil and stop there, but a pencil, eraser and sharpener set is small enough that there is little reason to.
4. A Clear Ruler, Thirty Centimetres
Needed for any paper with graph work, and clear so you can see the data points under the edge as you draw. Thirty centimetres rather than fifteen: a short ruler cannot span a full graph grid, and a line drawn in two halves never quite meets.
What matters: markings that start at the very edge of the plastic, numbers that have not worn off, and no flex. What to ignore: metal rulers, heavier and less useful because you cannot see through them. A basic clear thirty-centimetre ruler is the right answer and will outlast your degree.
5. A Scientific Calculator You Have Owned for Months
Two problems here, and only one is about buying anything. Permitted types differ between subjects on the same timetable — a calculator fine for one science paper may be barred from a maths paper two days later. Check the approved list your board publishes for your subject before you buy, not after.
The bigger problem is familiarity. A calculator you bought last week costs you marks, because the keystroke order for fractions, standard form and statistical functions differs between machines. Whatever you sit with should be the machine you did your past papers on.
Two rules catch people at the door: the memory must be cleared, and anything printed — the case lid with the function summary, any instruction card inside — stays outside the hall. What to ignore: anything programmable or graphing unless your subject explicitly permits it, because carrying one into a paper that bars it is a malpractice problem rather than a telling-off. If yours is missing or dying, an entry-level scientific calculator bought early enough to practise with does the job for almost every UK syllabus.
6. A Geometry Set for Maths and Science Papers
A compass, a protractor and a set square. Constructions, bisectors, loci and angle measurement all appear on maths papers and all require the physical tool — there is no working around a missing compass, and a hand-drawn circle earns nothing.
What matters is a compass that holds its radius. A loose hinge opens slightly as you draw and produces a spiral rather than an arc, which is the commonest way to lose construction marks with a compass in your hand. A protractor wants clear markings in both directions and a semicircle rather than a full circle, which is easier to line up on a printed angle.
Who should skip it: essay subjects entirely, and anyone whose maths exams are finished. Everyone else should have a maths geometry set in the bag, bought in time to use once or twice before the paper, because a compass you have never tightened is not much better than no compass.
7. An Analogue Watch, or No Watch at All
Anything with connectivity is out, and that includes fitness bands as well as smartwatches — not merely discouraged, but treated as unauthorised material. Expect to be asked to remove whatever is on your wrist and place it on the desk in view, which is now standard practice in many centres.
That rule is the argument for a plain analogue watch: readable face-up on a desk, incapable of connecting to anything, and it answers the question you are actually asking, which is how long is left. Halls have clocks, but a clock behind you is not much use when you are deciding whether to finish a paragraph.
What to ignore: anything with a hybrid or hidden smart feature — if a device pairs with a phone, leave it at home. A plain analogue wrist watch solves this permanently, and if buying one feels absurd for three weeks of exams, go without and sit where you can see the clock.
8. A Clear Water Bottle With the Label Off
Allowed in almost every centre, with one condition: no writing on it. That means peeling the label off a shop-bought bottle, or a reusable one with no printing on the body.
What matters: it does not leak in a bag, and it opens quietly with one hand — a lid that needs two hands and a loud crack is a minor social disaster in a silent hall. What to ignore: insulation, capacity claims and straw mechanisms that drip. A plain clear water bottle with the label removed is all this needs to be.
What UK Exam Halls Actually Provide
Less than students assume, and this is worth knowing before you decide what to carry.
- Provided, reliably: the question paper, an answer booklet, additional paper on request, a desk and chair, a clock somewhere in the room, and an invigilator who will bring you more paper if you raise a hand.
- Sometimes provided: a formula sheet or data booklet, but only where the specification says so. Some centres hand out rough paper; many do not.
- Not provided, despite the rumour: pens. Centres often keep a few spares for emergencies and will not refuse a student in trouble, but they are not stocked for you and you should never plan around them.
- Never provided: calculators, geometry sets, water.
The takeaway: the only reliable items are the ones you walk in with. That is the argument for three pens rather than one.
What to Skip
Half of a good kit is the things you deliberately leave out.
Correction fluid and tape. Not permitted in most UK halls, and pointless where tolerated — a single line through a mistake is accepted everywhere.
A full backpack. Most halls make you leave bags at the front, so the bag does nothing but carry your case to the door.
Lucky charms with writing on them. A plain object is usually fine; anything printed is a conversation at the door you do not need that morning.
Anything bought the night before. The point of a kit is that you have used it. New equipment on exam morning is how you discover your pen skips and your compass slips.
Building the Kit Before Study Leave
You do not need to buy everything at once, and most students already own two thirds of it. A sensible order: the transparent case and pen multipack first, since they apply to every paper you sit; then pencil, eraser, sharpener and ruler, which cover anything with a diagram in it; then the calculator and geometry set, only if your subjects need them and only early enough to practise with.
Once it exists, keep it packed. The clear case lives in the bag all season rather than being raided for homework, which is why a kit that existed in April is missing a ruler in June. For a longer stretch of study rather than exam days, our guide to the equipment you need for sixth form covers the wider setup.
The night before each paper, run one check: three pens, pencil, eraser, sharpener, ruler, the calculator if the paper needs it with its memory cleared and lid left at home, geometry set if needed, bottle with the label off, watch, and whatever identification your centre asks for. Ninety seconds, and the last point at which the kit can go wrong.
Final Thoughts
None of this makes you better at the subject. It removes the small number of ways a morning can derail before you have written anything — an opaque case emptied onto the desk, a pen that dies at the thirty-minute mark, a calculator you have never used in anger. Those failures are what this list is for, and they are avoidable for the cost of one trip to a shop. Settle the kit once, keep it packed, and spend the week before your exams on the paper rather than on your pencil case. If your papers are stacked close together, the sequencing advice in our guide to studying for multiple exams is the next thing worth reading, and for oral or practical components see how to study for an oral exam.
Frequently Asked Questions
What things to carry for an exam?
A transparent pencil case holding three identical black pens, two medium pencils, an eraser, a closed-barrel sharpener and a clear thirty-centimetre ruler; a permitted scientific calculator with its memory cleared and lid left at home; a geometry set for maths and science papers; a clear water bottle with the label removed; and whatever identification your centre asks for. Everything else waits in your bag at the front.
What are you allowed to bring into a GCSE exam?
Broadly: your own writing and drawing equipment, in a clear case or loose on the desk; a permitted calculator where the paper allows one; and a drink in a bottle with no writing on it. Not permitted: phones, smartwatches, fitness bands, earphones, notes of any kind, calculator lids with printed instructions, and anything else with a screen. Centres add their own rules, so read the instructions issued with your timetable — that document, not a general list, is what the invigilator works from.
What to do 30 minutes before an exam?
Nothing new. Check the kit once, use the toilet, drink some water, and stay away from the group outside comparing what they revised — that conversation has never helped anyone. If you need something to do, read your own summary sheet for a topic you already know well: it steadies you without introducing anything new to worry about.
