Myanmar Matriculation Chemistry · Put your knowledge to work in context.
The Myanmar Matriculation Chemistry page prepares candidates for the Grade-12 (အထက်တန်း) Chemistry paper sat at the end of upper secondary schooling in Myanmar. The subject is administered within the school system overseen by the Ministry of Education (ပညာရေးဝန်ကြီးဌာန), whose departmental structure includes the Myanmar Examinations Department (မြန်မာနိုင်ငံစာစစ်ဦးစီးဌာန) and the Department of Basic Education (အခြေခံပညာဦးစီးဌာန). This page is an independent study resource; it is not affiliated with, endorsed by, or operated by the Ministry, and it does not reproduce official question papers. The Ministry has announced that from the 2026-2027 academic year, Grade-12 curricula - Chemistry included - will be taught only with the 2026-2027 textbooks, and that the new curriculum is undergoing review and revision. The Myanmar Matriculation Chemistry case studies are 5 cases and about 2,472 words.
