Description
Cambridge IGCSE Chemistry Solved Past Papers + Video Explanations
Turn Cambridge theory and practical papers into a repeatable scoring method with 72 complete solved papers, precise calculations, full diagrams and step-by-step Paper 6 guidance.
What’s included
- High-value component coverage — Papers 4 and 6 together account for 70% of the Cambridge IGCSE Chemistry Extended route.
- Seventy-two complete papers — 36 Paper 4 and 36 Paper 6 sittings from 2021–2026 are solved from start to finish.
- Both syllabus codes covered — Cambridge 0620 and 0971 papers are presented under their correct official codes.
- Paper 4 theory mastered — Equations, moles, electrolysis, energy changes, rates, equilibrium and organic chemistry are worked in full.
- Paper 6 practicals fully explained — Planning, apparatus, qualitative analysis, separation, titration, calorimetry and rates are modelled step by step.
- Observation wording made precise — Colour changes, precipitates, gases and test results use the exact language examiners accept.
- Unknown-identification chains — Test selection, observations and conclusions are taught as a repeatable method.
- Authentic diagrams and graph work — Apparatus is completed, readings are taken at the correct precision and graphs use the paper’s own grid.
- Mark-by-mark model answers — Every scoring point is written clearly and shown with its own green tick.
- Mark schemes decoded in plain English — Acceptable answers, ignored wording, error-carried-forward rules and examiner shorthand are clarified.
- Examiner insight where available — Common misconceptions and costly answer patterns are drawn from official examiner reports or marking guidance.
- Difficulty guidance — Easy, medium and hard indicators help students spend revision time where it will make the greatest difference.
- Command-word coaching — State, describe, explain, deduce, suggest, justify and calculate are demonstrated in the form examiners reward.
- Original exam figures retained — Apparatus, data tables, spectra, graphs and reaction schemes stay with the exact question.
- Calculations worked line by line — Formula choice, substitution, rearrangement, units and final answer are all shown.
- Units and significant figures protected — Final answers model the precision and units needed to secure calculation marks.
- Revise by paper or by topic — Students can complete a realistic paper or drill one weak chapter across many sessions.
- Searchable online question finder — Filter by session, year, question, topic, difficulty and command word for focused practice.
