D. Official Bodies to Consult for Current Requirements

These are the authoritative sources for syllabuses, examination formats, and admission rules. They are listed so that readers can check current information; the book’s statements about the examination system are summaries and should be verified against them.

National Institute of Education (NIE), Sri Lanka: G.C.E. (A/L) syllabuses and teacher guides. https://nie.lk

Department of Examinations, Sri Lanka: examination circulars, past papers, and marking schemes. https://doenets.lk

University Grants Commission (UGC), Sri Lanka: admission to undergraduate courses, Z-score and cut-off publications. https://www.ugc.ac.lk

Ministry of Education, Sri Lanka: education reform announcements. https://moe.gov.lk

A note on verification. Descriptions of the syllabus structure, the stream and subject options, and the unit titles of the ICT syllabus come from secondary web summaries and a general encyclopaedic source, and they may lag behind official changes. The scientific and mathematical content follows standard textbooks and does not depend on administrative changes. Readers should rely on the official sources in Section D for anything that affects an examination decision.
