Cambodia Grade 9 Lower Secondary Diploma Exam exam-day guide
Cambodia Grade 9 Lower Secondary Diploma Exam · Prepare for the day ahead.
Your checklist
Admit card / candidate card (សំបុត្រប្រឡង) with photo
[needs_review] Most centres require a photo card issued by your school listing your candidate number, name and exam room. Format and issuing body differ between Phnom Penh and provincial centres, so confirm with your school's exam coordinator at least a week before. Carry it in a hard plastic sleeve or folder so it does not bend or get wet.
Supporting identity document
[needs_review] Bring the original national ID card, birth certificate or family book plus your school student card, whichever your centre lists. Photocopies are usually not accepted on their own. Confirm with the provider which document is mandatory in your province and whether a guardian's signature is needed if you have no national ID yet.
Three blue or black ballpoint pens plus one spare
Blue or black ink only; red and pencil-only answers are commonly rejected for written subjects. Test every pen the night before on scrap paper and discard any that skip or leak. Write your candidate number with the same pen you will use in the exam so the ink matches throughout the script.
Pencil, eraser and sharpener
Pencils are for diagrams, graphs, geometry constructions and multiple-choice shading only; final written answers stay in pen. Bring two HB pencils already sharpened, a soft eraser that does not smudge, and a small sharpener. Do not rely on the invigilator supplying stationery.
Geometry set: ruler, compass, protractor, set square
Mathematics and physics papers regularly include construction and measurement items. Check that the compass hinge is tight and the protractor markings are readable. A 30 cm ruler with clear millimetre marks prevents losing marks on scale drawings, where an unclear axis or missing unit costs as much as a wrong calculation.
Scientific calculator - subject to centre rules
[needs_review] Calculator policy varies by subject and by centre; some mathematics papers restrict or ban programmable models, and phones are never permitted as calculators. Confirm with the provider which model is allowed, and practise every calculation on the exact device you will carry, including trigonometry and standard-form keys.
Plain analogue wristwatch
[needs_review] A non-smart watch helps you pace a 90- or 120-minute paper without relying on a single wall clock that may be far from your seat. Some centres prohibit all watches, so confirm beforehand, and be ready to hand yours to the invigilator if asked. Smart watches and fitness bands must stay at home.
Clear water bottle and a small snack
Bring water in a transparent bottle with no label, and a light snack such as biscuits or a banana for the break between papers. Heavy fried food or energy drinks before a morning paper cause thirst and restlessness. Eat the snack outside the exam room, never at your desk.
Correct school uniform and footwear
[needs_review] Cambodian public examination centres normally expect the standard white shirt with dark blue or black trousers or skirt, and clean shoes. Rules on logos, belts and hairstyle are set locally. Confirm the dress requirement with your school so you are not turned away or delayed at the gate on the first morning.
Printed personal exam timetable
Write out your own schedule: date, session, subject, start time, room number and seat number. Keep one copy in your bag and one photo on a guardian's phone. Arrive for the room listed on your card, not for the room where you normally study; large centres use different buildings for different subjects.
Transport and emergency contact plan
Agree in advance who takes you, at what time, and what you do if the motorbike or tuk-tuk breaks down. Keep a written guardian phone number in your pocket, not only in your phone. For a 7:30 start in the rainy season, allow double the usual travel time.
Leave every phone and smart device at home
A phone, smart watch, earbud or any device that can store or transmit information must not enter the exam room, even switched off in a bag. Ask a guardian to hold your phone for the day. Possession during a paper is treated as a serious irregularity; confirm the exact penalty with the provider.
Plan the day
Confirm the official timetable, your room and seat number, and the documents your centre requires. Print or photograph the schedule. Then switch from learning new content to consolidating: rewrite one summary sheet per subject covering formulas, key dates, definitions and diagram labels. Finish one full past paper per major subject under timed conditions, marking yourself strictly against the mark scheme so you know which topics still lose marks.
Pack the bag completely: pens, pencils, geometry set, calculator, admit card, ID, uniform, water, snack. Do a timed dry run of the journey at the same hour as the real exam to check traffic and the correct gate. Fix your sleep schedule so you are awake by 5:30 or 6:00 on exam mornings. Review only your summary sheets and the marked mistakes from your practice papers.
Do light revision in 40-minute blocks with real breaks, and stop by early evening. Prepare clothes, shoes and documents by the door. Eat a normal familiar meal, avoid heavy oily food and energy drinks, and go to bed at your usual school-night time rather than much earlier. Do not attempt a new topic or an all-night review; exhausted recall is worse than a missing formula.
Wake, wash, eat a proper breakfast with rice or bread and some protein, and drink water. Re-check the admit card, ID, pens and calculator against your printed list. Leave home early enough to reach the centre 45 to 60 minutes before the start, which absorbs traffic and lets you find the room calmly. Use the toilet before entering the building, since toilet visits during a paper are usually restricted and cost you time.
Sit at your assigned seat, place your documents face up on the desk, and put everything else where the invigilator directs. Listen to the instructions and fill in your candidate number, name and subject on the cover exactly as they appear on your card. Check that you have every page of the question paper and that the printed subject and level are yours before the clock starts.
Read the whole paper before writing. Note the mark allocation per section and identify the questions you can answer confidently. Write a short time budget on the cover: for example, 90 minutes for 100 marks means roughly one minute per mark, plus ten minutes at the end for checking. Start with the section you know best to secure marks early and settle your nerves.
For mathematics and physics, show every step; method marks are awarded even when the final answer is wrong, and an unlabelled answer can score zero. For Khmer literature and history, answer in structured paragraphs with a clear opening claim, evidence and a short conclusion. Watch the clock at the halfway point and move on from any question that has swallowed more than its budget.
Stop writing new content and check instead: that every question number has an answer, that units and significant figures are present, that diagrams are labelled, and that no answer sits in the wrong section. Confirm your candidate number appears on every sheet you hand in. Cross out rough work clearly so it is not marked.
Leave the room quietly, drink water, eat your snack and move away from classmates who want to compare answers. Comparing questions after a paper cannot change your script and damages confidence for the next subject. Use the break to glance at your one-page summary for the next subject only, not to re-learn the paper you have just finished.
Keep your admit card and candidate number until results are published, because you may need them to check results or request a review. Ask your school when and where results are posted and how to appeal a grade. Confirm with the provider whether any subject paper has a separate oral or practical component you still need to sit.
Rules to check
Carry photo identification every session. The name and spelling on your script must match your admit card and ID exactly; if a document shows a different spelling from your school record, sort it out with your school before exam week rather than at the gate. [needs_review] Confirm with the provider which single document is accepted if the names differ.
No phone, smart watch, earbud, camera or any storage device may enter the exam room. Leave them with a guardian for the day. If a device is found on you during a paper, expect the script to be cancelled and possible further disciplinary action; confirm the exact procedure in your centre's regulations.
Arrive before the scheduled start. Centres normally admit late candidates only for a short window and give no extra time, and some refuse entry after the first paper has begun. Confirm the late-admission cut-off with the provider instead of assuming you will be let in.
You may not leave the room during the early part of a paper, and once you leave you normally cannot return to continue writing. Raise your hand and wait for an invigilator for any need; do not call out, borrow stationery from a neighbour, or turn around to talk.
Write in Khmer for Khmer-literature, history, geography and moral-civics papers, and in English for the English paper. Answer in the language the paper is set in unless the instructions say otherwise; an answer in the wrong language may score nothing even if the content is correct.
Any attempt to copy, pass notes, use unauthorised material or communicate with another candidate is treated as cheating and can void the whole subject result, not only the question involved. Keep your eyes on your own script and your body turned towards your desk.
Scoring and grading: each subject is marked out of 100 and results are reported as a grade with a subject average used for progression to upper secondary. Grade boundaries, compensation between subjects and the pass mark change between years, so check your school's official notice rather than relying on last year's numbers. [needs_review]
