IGCSE Chemistry is one of the most demanding Cambridge subjects — and Save My Exams is a popular revision tool for it. But if you’ve hit the paywall, want more interactive practice, or need something that teaches you how to write Chemistry answers as well as what to write, here are the best free alternatives for 2026.

Why Students Search for a Save My Exams Chemistry Alternative

• Paywall friction — a meaningful portion of Save My Exams Chemistry resources require a subscription
• Notes without technique — knowing the chemistry doesn’t automatically translate to scoring marks if you don’t write in the way Cambridge mark schemes expect
• No live help — revision sites can’t explain a concept you genuinely don’t understand
• Particle-level explanations — Chemistry mark schemes are highly specific about particles (ions vs molecules vs electrons); Save My Exams doesn’t always bridge this gap clearly

1. Tutopiya — Mark Scheme Technique + Free Tools

Best for: Students who know their Chemistry but keep losing marks on explain questions

The most distinctive Tutopiya tool for Chemistry students is the Mark Scheme Decoder — IGCSE Chemistry 0620.

Chemistry is notorious for mark scheme precision — “ions are free to move” earns the mark, “the particles move” does not. The Mark Scheme Decoder addresses this directly:

• Auto-marked practice questions for every Chemistry question type (State, Describe trend in data, 3-mark Explain, 6-mark extended response, Compare)
• Instant feedback on which mark points you hit — shows exactly which keyword concepts you included and which you missed
• Model answers (unlocked on sign-up)

Other free Tutopiya Chemistry tools:

• Common Mistakes — IGCSE Chemistry — specific misconceptions that cost Cambridge Chemistry students marks
• Flashcard Maker — build Chemistry definition and equation flashcard decks
• Grade Boundary Tracker — know the raw mark needed for each grade in IGCSE Chemistry

2. ZNotes — Free Chemistry Notes

Best for: Free, concise Cambridge-aligned Chemistry notes

ZNotes provides free IGCSE Chemistry revision notes in PDF format, following the Cambridge 0620 syllabus. They cover all major topics — atomic structure, bonding, stoichiometry, organic chemistry — in a condensed format.

Limitation: Notes only — no practice questions or mark scheme guidance.

---

3. PapaCambridge — Past Papers

Best for: Full Cambridge IGCSE Chemistry past paper archives

PapaCambridge hosts every Cambridge IGCSE Chemistry (0620) past paper and mark scheme for free. Past paper practice is essential for Chemistry — the question formats are consistent and recognisable once you’ve done enough papers.

4. Cognito (YouTube) — Video Explanations

Best for: Visual learners who need to see reactions and processes explained

Cognito’s YouTube channel covers Cambridge IGCSE Chemistry topics in concise animated videos. Particularly useful for electrolysis, rates of reaction, and organic chemistry where diagrams and animations add clarity that notes can’t provide.

5. Chemrevise.org — Free A-Level and IGCSE Notes

Best for: More detailed Chemistry notes than ZNotes

Chemrevise provides comprehensive free Chemistry notes. While primarily aimed at A-Level, many topics overlap with IGCSE content — particularly useful for stoichiometry, bonding, and equilibrium.

The Most Commonly Lost Marks in IGCSE Chemistry

These are the areas where Cambridge Chemistry students most often lose marks — and where Save My Exams’ static format is weakest:

1. Particle-level precision in explain questions. Cambridge awards marks for naming the correct particles — “ions”, “electrons”, “molecules” — and saying what they do. “The liquid conducts electricity” earns 0; “the ions are free to move and carry charge” earns the mark.

2. Conditions in mechanism questions. The Haber process requires ~450°C, ~200 atm, iron catalyst. The Contact process requires ~450°C, V₂O₅ catalyst. Missing any condition loses a mark.

3. Ionic equations. Many students write molecular equations when the mark scheme requires ionic equations.

The Tutopiya Mark Scheme Decoder includes auto-marked questions specifically targeting these areas.
