JC Science exam-day guide
JC Science · Prepare for the day ahead.
Your checklist
Photo ID and admission document
Bring the exact identification the provider requires and any admission ticket or confirmation email. The accepted ID type and whether a printed ticket is mandatory vary by centre, so confirm with the provider before the day.
Confirmed test centre location and arrival time
Check the address, building entrance, and reporting time on your admission document. If the venue is unfamiliar, plan the route in advance; some centres require earlier arrival for registration and seating.
Approved calculator
Bring a calculator only if the provider permits one, and check the allowed model list. Some specifications restrict programmable or graphical calculators; confirm with the provider which models are accepted and whether spares are allowed.
Spare pens, pencils, eraser, and sharpener
Pack at least two working pens or pencils plus an eraser. For graph work, a sharp pencil and ruler are useful; check whether the provider supplies stationery or expects you to bring your own.
Ruler and protractor
These are commonly needed for graph plotting and angle measurement in science papers. Confirm whether they are on the permitted equipment list for your specification.
Clear pencil case or transparent bag
Many centres require equipment to be visible in a clear case or bag. If you are unsure of the local rule, confirm with the provider and keep packaging minimal.
Water in a clear, label-free bottle
Drinking water is often allowed if the bottle is transparent and the label is removed. Check the centre's rules, since some venues restrict drinks at the desk.
No phone or smart device at the desk
Leave phones, smartwatches, and wearable devices switched off and stored as instructed. Possession at the desk can be treated as malpractice even if the device is off; confirm the storage arrangements with the provider.
Know your candidate number and centre number
Write these on every answer booklet and any separate answer sheet as instructed. They are usually on your admission document; if not, ask the invigilator before the paper starts.
Read the front cover instructions
Check the paper code, tier or unit, and the time allowed before you begin. Report any mismatch or missing pages to the invigilator immediately.
Plan for timing and breaks
Confirm the total duration and whether supervised breaks are permitted. Toilet access during the test is usually escorted and may not extend your time; ask the provider about any access arrangements you need.
Access arrangements confirmed in advance
If you need extra time, a reader, a separate room, or other support, it must normally be approved before the exam day. Confirm with the provider well ahead; arrangements cannot usually be granted on the day.
Plan the day
Switch from learning new content to consolidating. Re-read your practical notes on variables, controls, apparatus, and safety, and rehearse the standard write-up structure: aim, hypothesis, method, risk assessment, results table, graph, conclusion, evaluation. Practise reading tables and graphs quickly, including identifying anomalies and describing trends. Check the permitted equipment list and confirm your calculator meets it. Locate your ID, admission document, and stationery, and resolve any access-arrangement questions with the provider now rather than on the day.
Do a light review only: key formulae, units, significant figures, and the difference between accuracy, precision, reliability, and validity. Pack your bag with ID, admission document, approved calculator, spare pens and pencils, eraser, sharpener, ruler, protractor, and clear case. Confirm the journey and set two alarms. Avoid cramming new material late at night; sleep is more useful than one more past paper. Check the provider's website once for any venue or timing change.
Eat a normal breakfast and arrive with time to spare, allowing for transport delays. Keep your phone switched off and stored before you enter the secure area. At registration, present your ID and admission document, find your seat, and check that the paper code and page count are correct. Listen carefully to the invigilator's instructions, fill in your candidate details, and read the front cover before the start signal.
Read the whole paper briefly and allocate time by mark weighting, leaving a few minutes to check. Answer the questions you find easiest first if that helps confidence, but make sure every question is attempted. For practical questions, name the independent, dependent, and control variables explicitly, state how measurements are taken, and include units. When plotting graphs, use a sharp pencil, label both axes with quantity and unit, use a sensible scale, and draw a line of best fit rather than joining every point. Show working for calculations and give answers to an appropriate number of significant figures. For evaluation questions, identify a specific source of error and suggest a concrete improvement. If you run out of time, write brief bullet points for remaining answers rather than leaving blanks, and cross out rough work you do not want marked.
Rules to check
Bring the identification and admission documents the provider specifies. If you are unsure which forms of ID are accepted, confirm with the provider before the exam day, because entry may be refused without valid ID.
Follow all invigilator instructions about seating, equipment on the desk, and when you may write. Do not open the paper or write in the answer booklet until you are told to start, and stop writing immediately at the end signal.
Do not bring unauthorised materials or devices into the secure area. Phones, smartwatches, and notes must be stored as instructed; possession at the desk can be treated as malpractice regardless of intent, so confirm storage arrangements with the provider if unclear.
Raise your hand if you need to leave the room, need more paper, or feel unwell. Toilet visits are normally escorted, and the time lost is usually not added back, so plan ahead; confirm the centre's specific policy with the provider.
Do not communicate with other candidates once the test has begun, and do not attempt to view others' work. Any suspected malpractice should be reported to the invigilator rather than handled between candidates.
Write in the format the paper requires, such as black or blue pen for prose and pencil for graphs, and keep answers inside the marked areas. If you are unsure which ink or format is required, confirm with the provider or ask the invigilator before starting.
Scoring is normally based on the marks shown on the paper, with credit for correct working and for valid practical reasoning such as identifying variables and suggesting improvements. Do not assume that a correct final answer without working earns full marks; the exact marking approach is set by the provider.
If you believe there was a problem with the paper, the venue, or your access arrangements, tell the invigilator on the day and then contact the provider promptly. Do not rely on informal assurances; confirm the official complaints or special consideration process with the provider.
