Guinea Bac Sciences Expérimentales exam-day guide
Guinea Bac Sciences Expérimentales · Prepare for the day ahead.
Your checklist
Convocation / inscription proof
Bring the convocation or registration document issued for the Bac session. The exact document name and whether a printed copy is mandatory vary by centre - confirm with the provider (Direction Préfectorale/Communale de l'Éducation or your school) before the exam day.
National identity document
Bring a valid pièce d'identité (CNI, passport, or another officially accepted document). Check with your centre which documents are accepted and whether a photocopy suffices if the original is lost.
Black or blue ballpoint pens (spares)
Bring at least two pens of the same colour plus a spare. Use only the ink colour permitted by the subject instructions; red ink is generally reserved for correctors, but confirm the centre's instruction.
Pencil, eraser, and sharpener
Needed for graphs, sketches, and any diagrams in the SVT, physics, or chemistry papers. A soft pencil (HB or 2B) and a clean eraser are enough.
Ruler and graduated ruler
A straight ruler is essential for drawing axes, tables, and geometric constructions in physics/chemistry and for neat, readable tables in SVT.
Scientific calculator
Bring a calculator you know well, with fresh batteries. Programmable or graphing models may be restricted depending on the subject and centre - confirm with the provider which models are allowed, and clear any stored programs if required.
Simple watch (no smart features)
A basic wristwatch helps you manage time. Smartwatches and phones are usually prohibited in the exam room; confirm the centre's rule on what must be left outside.
Water bottle and light snack
A transparent bottle of water and a small snack for before/after long sessions. Check whether food and drink are allowed inside the exam room.
Nothing written on hands, arms, or clothing
Remove any notes, formulas, or annotations from your hands, arms, pencil case, and calculator cover before entering. Any suspicious writing can be treated as attempted fraud.
Know your centre, room, and seat
Locate your exam centre and, if published, your room and seat number in advance. Arrive early enough to find the room without stress.
Plan transport and arrive early
Plan your route and leave a margin for delays. The exact arrival time and late-entry rule vary by centre - confirm with the provider rather than relying on a general rule.
Rest and normal meals
Sleep well and eat a normal breakfast. Avoid last-minute cramming of new material; review only summaries, formulas, and method sheets.
Plan the day
Stop learning new content. Rework your summary sheets for each subject: key definitions, formulas, units, and standard methods (e.g., how to structure a physics calculation, how to analyse a document in SVT). Redo one or two past papers under timed conditions per subject, then correct them carefully. Identify your recurring mistakes and write them on a single 'watch-out' sheet. Prepare your bag and documents so nothing is left to the last day. Keep normal sleep hours.
Do a light review only: read your summary sheets and the 'watch-out' sheet, and glance at formula lists. Do not start a new chapter. Check the exact time, room, and address of the exam and plan transport. Prepare the checklist items (ID, convocation, pens, calculator, ruler, watch, water). Pack the bag the evening before. Eat a normal dinner, avoid heavy screen use, and go to bed at a reasonable hour.
Eat a real breakfast and hydrate moderately. Re-read your summary sheets briefly - no new material. Take your prepared bag and leave early with a margin for transport. On arrival, locate your room and seat, keep calm, and avoid comparing notes with other candidates, which only increases stress. Switch off your phone and put it away before entering the room.
Write your identification details exactly as instructed. Read the whole paper first (a few minutes) and note the marks or weighting of each exercise. Choose the order that secures the easiest marks first, then return to harder parts. Allocate time per exercise and keep 5–10 minutes at the end to check units, significant figures, and that every question has been answered.
Show your reasoning: state the formula, substitute values, give the unit, and box or underline the final answer. For SVT, use precise vocabulary and structure answers (observation, interpretation, conclusion). For document-based questions, cite the document explicitly. If you are stuck, move on and come back. Keep handwriting legible and lay out calculations in clear steps so the corrector can follow your method.
Check that your name and identification are written, that no question is left blank, that units and significant figures are consistent, and that tables and graphs are labelled (axes with quantity and unit). Make sure your final answers are clearly identifiable.
Rules to check
Bring the required identity document and convocation; without them, entry may be refused or delayed. The exact accepted documents and the procedure for a lost document must be confirmed with the provider.
Electronic devices such as phones and smartwatches are generally prohibited in the exam room; switch them off and leave them where the centre instructs. Confirm the centre's specific policy with the provider.
Any notes, formulas, or annotations not authorised for the subject are treated as attempted fraud and can lead to sanctions. Only bring authorised materials into the room.
Follow the invigilators' instructions at all times: seating, start and end times, and the collection of papers. Do not communicate with other candidates during the test.
Breaks and permission to leave the room during a session are governed by the centre's rules; ask an invigilator rather than leaving on your own. Confirm the policy with the provider.
Marking follows the official subject rubric: method and reasoning earn marks, not just the final answer. Write clearly, show steps, and give units.
If you believe there is an error in the paper or a problem during the test, raise it calmly with an invigilator and ask for it to be recorded; do not alter the paper yourself.
