A-level chemistry command words
Command words indicate the type of response required. For example, describe asks for relevant features or trends, while explain asks for reasons or mechanisms. Read the whole question and use your board’s published guidance, because the expected detail depends on the context and number of marks.

Marking labels used in InkChemistry questions
Every question in this library carries an original mark scheme written point by point. These labels belong to those schemes and are not necessarily used by every awarding body.
- A
- Answer or accuracy point.
- B
- Independent point, awarded regardless of the other marks.
- M

Mark a written answer against the scheme supplied with the question rather than by feel, and record the points you missed.
