Topics by unit
Foundation for all other topics. Reverse percentage and compound interest appear in almost every Paper 1 — learn the direct formula rather than the step-by-step method.
Algebraic manipulation is tested heavily in Paper 2. Factorising quadratics by inspection is faster than the formula — practise until it's automatic.
Circle theorems require you to state the theorem name for full marks. Bearings must be written as three digits (e.g. 045°, not 45°).
Formulae are not given — memorise area of circle, cone, sphere. Similar shape ratios (k², k³) appear frequently in the last few questions of each paper.
Cumulative frequency and histograms are reliably tested. Remember: histogram y-axis is frequency density (frequency ÷ class width), not frequency.
Commonly searched questions
Work through at least five years of past papers from Cambridge. For Pakistan and Malaysia students, past papers from your local board (FBISE, SPM) are also important as question styles differ slightly. Always check the mark scheme — O-Level awards marks for method steps, not just final answers.
Cambridge O-Level (4024) past papers are available on the Cambridge International website and on third-party revision sites. Pakistan students can find FBISE and provincial board papers on their respective board websites. Malaysian SPM papers are available via the Malaysian Examinations Board (Lembaga Peperiksaan).
For Cambridge O-Level, grades run from A* (highest) to G. A grade C or above is widely considered a pass. For university entry in Pakistan and Malaysia, most programmes require at least a B. Check your institution's specific requirements.
The content is nearly identical — both are based on the same Cambridge specification. IGCSE (0580) has a Core and Extended tier; Extended covers additional topics like functions, transformations, and vectors in more depth. O-Level (4024) is a single syllabus closer to the IGCSE Extended level.
