Concours Centrale-Supélec exam-day guide
Concours Centrale-Supélec · Prepare for the day ahead.
Your checklist
Convocation and photo ID
Bring the convocation (summons) issued for your session together with a current photo ID. The exact ID accepted and whether a printed convocation is required can vary by centre; confirm with the provider (the organising school or the concours service) which documents are mandatory and in what form.
Check your centre, room and access details
Centres are often host lycées or engineering schools rather than the organising institution. Verify the address, the entrance to use, and the reporting time on your convocation, and plan the route in advance. If anything on the convocation looks wrong, contact the concours service before the exam day.
Know which épreuves are on which day
Centrale-Supélec written sessions run over several days with different subjects (for example mathematics, physics, français/philosophy, and for some filières an informatics or engineering-science paper). List your personal schedule of papers, durations, and start times so you do not mis-pack or arrive on the wrong morning.
Authorised calculator and its rules
Calculator rules differ between concours and can change from year to year, and some papers forbid calculators entirely. Check the current official notice for your session and filière, and confirm with the provider whether a specific model or a 'mode examen' configuration is required. Do not assume last year's rule still applies.
Spare pens, pencils, eraser, ruler, and geometry kit
Bring several dark-ink pens, pencils for diagrams, an eraser, a ruler, and any compass/protractor you normally use for physics or engineering-science figures. Bring your own supply; do not count on borrowing from neighbours.
Watch or small clock
Many exam rooms have no visible clock, and phones are not usable as timekeepers. A simple wristwatch (not a smartwatch) helps you allocate time across a long paper. Confirm with the provider whether any watch restrictions apply in your room.
Water and a small snack for long sessions
Papers can run several hours. Bring a clear bottle of water and something quiet to eat during authorised breaks, subject to the room's rules. Confirm with the provider what is allowed at your desk.
Leave the phone and connected devices behind or switched off
Smartphones, smartwatches, and any connected device are typically prohibited at the desk and possession can be treated as fraud. The safest approach is to leave them at home or hand them in as instructed. Confirm with the provider the exact policy for your centre.
Read the instructions on the subject paper carefully
Check the number of pages, the choice of exercises or problems, and any instructions about which questions are compulsory. Note the total duration and the marks or weighting if given, and plan your time before writing.
Prepare your candidate number / identification details
You will usually have to write identifying information on each copy and sometimes on a separate sheet. Have your convocation details at hand so you copy them accurately. Confirm with the provider what identification is required on the answer scripts.
Plan transport and a margin of time
Aim to arrive well before the reporting time; latecomers may be refused entry once a paper has started. Check for transport disruptions and identify a fallback route. Confirm with the provider the exact late-arrival rule for your centre.
Rest and logistics the night before
Sleep, prepare clothes and bag the evening before, and set two alarms. Avoid last-minute cramming of new material; a short review of formula sheets and method checklists is more useful.
Plan the day
Confirm the full schedule of your papers: dates, start times, durations, and rooms. Re-read the current official notice on authorised materials (especially calculators) and check with the provider if anything is ambiguous. Assemble your convocation, ID, stationery, and calculator in one bag.
Do targeted revision rather than new topics: formula sheets, standard methods, and past-paper timing. Practise one timed section under exam conditions to calibrate how long you take per exercise.
Check the journey to the centre, including any transport works or strikes, and decide your departure time with a comfortable margin. If you are staying away from home, confirm the accommodation and the route to the centre.
Do a light review only: reread your summary sheets and the instructions for each paper type. Stop working early enough to sleep properly. Prepare clothes, food, water, and the bag, and place the convocation and ID where you cannot forget them.
Recheck the reporting time and room, set alarms, and confirm any last-minute messages from the concours service. Avoid intensive last-minute memorisation, which tends to increase anxiety without improving performance.
Eat a proper breakfast, arrive at the centre with a wide margin, and locate the room and the toilets before the start. Keep your convocation and ID accessible for checking. Switch off and stow your phone as instructed.
Once seated, read the cover page of the subject carefully: number of pages, compulsory questions, choice of exercises, and any instructions. Note the start and end times and sketch a time budget before you begin writing.
Work in passes: a first pass on the questions you can do confidently, then return to harder parts. Write clearly, show your reasoning, and do not leave blanks where a method or partial result could earn marks. Watch the clock at fixed checkpoints rather than constantly.
If you finish early, use the time to check calculations, units, and that you have answered every required question. Do not leave the room until permitted, and follow the invigilator's instructions for handing in scripts and materials.
Rules to check
Bring the convocation and a valid photo ID and present them when asked. The exact accepted forms of ID and whether a printed convocation is required vary by centre; confirm with the provider before the exam day.
Phones, smartwatches, and other connected devices are generally prohibited at the desk, and possession can be treated as fraud. Hand them in or leave them behind as instructed; confirm with the provider the exact policy for your centre.
Only authorised materials may be used. Calculator rules differ between concours and filières and can change; check the current official notice and confirm with the provider rather than relying on memory or hearsay.
Follow the invigilators' instructions at all times, including on seating, talking, leaving the room, and handing in scripts. Breaches of exam conduct can lead to sanctions, including cancellation of results.
Late arrival may mean refusal of entry once a paper has started, and early departure may be restricted. Confirm with the provider the exact late-arrival and leaving rules for your centre.
Breaks and access to water or the toilets are usually at the invigilator's discretion and may be escorted. Ask before the paper starts what the procedure is, and confirm with the provider if you have a specific need.
Scoring is generally based on the written papers with defined weightings per subject and filière, and some schools may invite shortlisted candidates to an oral stage. The exact coefficients and oral format are set each year; confirm with the provider and read the current official notice.
Write identifying information accurately on every script as instructed, and do not write anything that could reveal your identity where anonymity is required. Confirm with the provider the identification requirements for your session.
