One marking point = one mark
CCEA schemes list creditworthy points, each worth one mark. A 4-mark question needs four distinct ideas, not one idea written four ways. Count your points before you move on.
CCEA Biology mark schemes, explained
Most students read a CCEA mark scheme to check an answer. The students who move a grade use it as a wording list. This page explains how CCEA A-Level Biology mark schemes are constructed, then gives you a routine for marking your own answers without being kind to yourself. Mark schemes are published by CCEA alongside each past paper.
Open CCEA’s official mark schemesSix rules CCEA mark schemes follow
The wording in the scheme is the wording that scores
'Water potential' is credited; 'concentration of water' usually is not. 'Sodium-potassium pump' is CCEA's term. Learn the exact noun phrases, not paraphrases.
Semicolons separate alternatives
Where a scheme shows alternatives separated by a slash or 'or', any one of them scores. Where points are listed on separate lines, you need each line for full marks.
Extended responses carry QWC credit
On CCEA extended-response questions, quality of written communication is assessed alongside content: logical sequence, correct biological terminology, and clear spelling and grammar.
Data answers must quote figures
'It increases' is rarely a mark. Quote the values with units, and where possible give the change or rate you calculated from them.
No marks for contradiction
A correct point followed by a wrong one in the same sentence cancels. Do not hedge with a second guess after you have written the right answer.
Command words decide which marking points exist
| Command word | What the scheme rewards |
|---|---|
| State / Give / Name | A short factual answer. No explanation needed — and no marks for adding one. |
| Describe | Say what happens, in order, without saying why. Trends in data need figures quoted. |
| Explain | Give the reason or mechanism. Every 'because' should be a separate marking point. |
| Compare | Make linked statements about both things in the same sentence, not two separate lists. |
| Suggest | Apply what you know to an unfamiliar context. There is usually more than one creditworthy answer. |
| Discuss / Evaluate | Weigh both sides and reach a judgement. These carry QWC credit, so structure matters. |
The six-step self-marking routine
- 1Print or open the CCEA mark scheme for the exact series you sat.
- 2Mark in a different colour and never with the paper still open beside your answer.
- 3Tick only where your wording matches a marking point — 'I meant that' is not a mark.
- 4Write the missed marking point out in full, in CCEA wording, beside your answer.
- 5Tag each lost mark to a spec topic so your revision list builds itself.
- 6Re-attempt only the dropped questions 48 hours later, closed-book.
