Edexcel A level Chemistry revision.
Ilmino organises A level Chemistry around the Edexcel A level Chemistry 9CH0 specification, so every topic, every required piece of practical work and every mark scheme a student sees belongs to the board they are actually sitting.
The exam, in short
How Edexcel examines A level Chemistry.
- Specification
- A level Chemistry (9CH0)
- Papers
- Three written papers, plus the practical endorsement, which is reported separately from the A level grade.
- Tiers
- Single tier. There is no Foundation or Higher entry at A level.
- First exam series
- Summer 2017
Spec aligned
Every topic on the Edexcel specification.
The question bank is grouped by this board's specification, not by a generic topic list, so a student works through the same headings their teacher and their revision guide use.

Marking
How marking follows Edexcel.
Ilmino stores an examiner-style mark scheme for every question, written per board. An answer is marked against the wording Pearson Edexcel credits, not against a general idea of what is right.
- Each mark is awarded or withheld on its own, with the mark-scheme point it maps to shown beside the answer.
- Command words are read the way Edexcel uses them, so describe, explain, evaluate and calculate are each held to their own standard.
- The phrase an examiner is looking for has to appear. A right idea in the wrong words loses the mark here, exactly as it would in the exam.
- Handwritten working is photographed and marked line by line, so method marks survive an arithmetic slip.
- When a mark is lost, Lumi explains which mark-scheme point was missed and what would have earned it.
