The Compulsory Part of HKDSE Mathematics is distinct from the Extended Part modules M1 and M2. Prepare the required core mathematics before adding extension-specific material. The compulsory assessment includes conventional and multiple-choice questions.
M1 and M2 are separate extension choices; they are not substitutes for the compulsory papers. Official examination information and the current syllabus take priority. AskSia is an independent study tool.
A multiple-choice shortcut is only useful when its conditions hold. Learn when a diagram, exact substitution or algebraic method is more dependable.
These are study priorities and examples, not published assessment weightings. Use your own syllabus, paper requirements and recent attempts to decide where to spend the next session.
