How to use past papers properly (most students do it wrong)

Phase one: papers as lessons

Early in revision, try questions with your notes available if needed, then check the scheme. Compare the scientific meaning and method, including accepted alternatives, rather than assuming that different wording is wrong. “Temperature rises” and “internal energy increases” describe different ideas; whether either is appropriate depends on the question.

Phase two: diagnosis

Keep an error log with three columns: didn't know the physics, knew it but wrote it wrong, careless slip. After three papers the log tells you precisely where your marks are leaking — and for most students, the second and third columns dwarf the first. That discovery redirects revision from re-reading notes (which fixes column one) to answer training (which fixes the columns that actually cost grades).

Use the syllabus for coverage and marked questions to diagnose gaps.

Phase three: rehearsal

Only in the final weeks do papers become mock exams: full papers, strict time, no notes, marked honestly against the scheme. This is rehearsal for the performance — timing, question order, the discipline of moving on when stuck. My student Nadia described her real IGCSE as feeling like a paper she had already seen; that is what three phases of proper paper work produces.

One warning: never sit the most recent two years' papers early. Save them as your final dress rehearsals — they are the closest thing to the exam you will face.
