How to Study for Cambridge IGCSE — Subject by Subject

Different IGCSE subjects reward different study habits. Here's what actually works for maths, sciences, English, and the humanities.

IGCSE spans a genuinely wide range of subjects, and treating them all the same way — reading notes, then hoping it sticks — wastes time on subjects that need a different approach entirely.

For Mathematics and the sciences, worked examples and past-paper practice matter more than re-reading notes. These subjects are tested on application, not recall, so the fastest way to improve is doing questions, checking them against a mark scheme, and specifically drilling whatever type of question you got wrong.

For English and humanities subjects, the skill being tested is structured argument backed by evidence, not memorised facts recited in isolation. Practising short written responses under timed conditions — and comparing them against the mark scheme's language, not just your gut sense of whether it 'sounds right' — closes the gap between a good answer and a top-mark one faster than anything else.

Languages sit in their own category: consistent short daily practice beats occasional long sessions, and speaking practice — even alone, out loud — matters more than most students give it credit for, since listening and speaking components are often where marks are lost through simple lack of practice rather than lack of ability.

Across every subject, Cambridge publishes past papers and mark schemes openly, and working through several years' worth under real timed conditions remains the single most reliable form of preparation — it teaches you exactly how marks are actually awarded, not just what the right answer is.
