Cambodia Grade 9 Lower Secondary Diploma Exam

It certifies completion of lower secondary education and is normally used for progression or admission to upper secondary school; some specialised schools also use results for selection. Exact rules change annually and are set by MoEYS. Check moeys.gov.kh and your provincial education office for current admission criteria.

Expect Khmer literature and language, mathematics, physics, chemistry, biology and earth science, history, geography, moral-civic education, and a foreign language, commonly English. The exact subject list and weighting for your year are published by MoEYS. Confirm with your school because subject arrangements can change.

Papers are written and subject-specific, administered over several days. Expect a mix of multiple-choice, short-answer, calculation, and longer constructed-response or essay items depending on the subject. Khmer and history lean toward extended writing; mathematics and science require shown working. The precise paper structure is set in the current MoEYS instructions.

It is a curriculum-based national exam, so difficulty comes from breadth and from writing full answers under exam conditions, not from trick questions. Students who have kept up with grades 7–9 and practised structured essays and calculations usually find it manageable. Weak handwriting speed and incomplete working are common causes of lost marks.

Retake rules are set by MoEYS and can change by year and by candidate category, so no fixed answer applies. Ask your school director or provincial education office for the current rule, deadlines, and any conditions on retaking. The ministry publishes notices at moeys.gov.kh.

Start with your weakest two subjects and protect weekly time for them, then rotate the rest so no subject goes too long without review. Give mathematics and science regular problem sessions, and schedule essay practice for Khmer and history. Increase past-style practice in the final weeks.

Memorising notes without practising written answers. The exam rewards clear structure, correct method, and enough detail, so practise producing full responses from memory and have teachers mark them. Also common: ignoring diagrams and data questions in science and geography, and running out of time on essays because of poor planning.

Rules on calculators and other aids vary by subject and year and are announced in the ministry exam instructions. Do not assume a calculator is permitted; learn to do the core arithmetic and algebra by hand. Confirm the current rule with your school before exam day.

Begin serious revision at least one full semester before the exam, with light review earlier. Early months should rebuild weak topics; the last weeks should be timed practice and feedback. Cramming does not work well because the exam samples three years of curriculum across many subjects.

Results are reported by subject, and the consequences of a weak subject depend on the current rules for progression and certification. Do not rely on rumour; ask your school director or provincial office how subject results affect your certificate and upper-secondary placement, and check MoEYS notices.
