Cambridge IGCSE Chemistry, marked to the mark scheme.

Practise every topic on the Cambridge specification and get each answer checked against the published scheme, point by point — with the wording that would have earned the marks you missed.

Built for Cambridge, not adapted to it.

Cambridge IGCSE Chemistry spans 12 topics, from States of Matter to Experimental Techniques and Chemical Analysis, and Exaim covers all 49 subtopics — with practice written for the Cambridge specification rather than adapted from another board's.

Chemistry rewards method — the steps of a calculation, the state symbols, a correctly balanced equation — and a right answer reached the wrong way still drops the marks. Exaim marks your written answers the way Cambridge's own examiners do, one marking point at a time, so every question shows you where a real mark was won or lost.

What you get with every Cambridge Chemistry course.

The same thing in every subject: real exam questions, marked properly, and a clear next step.

Marked like an examiner would

Write the answer in full and get it checked against your board’s published scheme, point by point, with the wording that would have earned each mark.

Built for your exact board

Not a generic summary written for everyone. Questions, notes and mark schemes all follow the specification you are actually sitting.

Practice, papers and timed mocks

Topic questions when you are learning something, full papers under exam conditions when you are ready to find out.

Handwritten work included

Photograph a written answer or a diagram and it is marked the same way — so you can revise on paper if that is how you work.

A plan that reorders itself

Every mark you drop becomes scheduled practice, so the weakest topic is always next and you never open the app wondering what to do.

How Cambridge Chemistry practice actually works.

Not a video you watch. A question you answer, marked the way an examiner would.

  1. 01

    Answer a real exam question

    Type it, write it on paper and photograph it, or draw the diagram. Full sentences, the way you would in the exam.

  2. 02

    It is marked point by point

    Checked against your board’s published mark scheme, one mark point at a time — with the wording that would have earned the ones you missed.

  3. 03

    Your plan moves

    Every mark you drop becomes scheduled practice. The weakest topic is next, so you never open it wondering what to do.

Common questions.

How is Cambridge IGCSE Chemistry marked on Exaim?

You write a real exam-style answer and it is marked against Cambridge's published mark scheme, point by point — the same marking points an examiner uses. You see exactly which points you earned, which you missed, and the wording that would have earned them.

How many topics does Cambridge IGCSE Chemistry cover?

The whole specification: 12 topics, from States of Matter to Experimental Techniques and Chemical Analysis, broken into 49 subtopics you revise and get tested on. Every one has practice, and the full list is on this page.

Is this built for Cambridge, or a generic chemistry course?

Built for Cambridge. The questions, the topics and the marking all follow the Cambridge specification — not one generic chemistry course with a board's name on the front.

Can I try Cambridge IGCSE Chemistry for free?

Yes — start free with no card. You can practise Chemistry questions and see exactly how the marking works before you decide anything.

I sit a different board — is Chemistry covered for others?

Yes. IGCSE Chemistry is covered for Edexcel and Oxford AQA too, each built for that board's own specification. The links are further up this page.
