, MARK SCHEME – A-LEVEL BIOLOGY – 7402/3 – JUNE 2021
Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevantquestions,
by a panel based on subject teachers. This mark scheme includes any amendments made at the standardisation
events which all associates participate within and is the scheme which was used by them within this examination.
The standardisation process ensures that the mark scheme covers the students’ responses to questions and that
every associate understands and applies it within the same correct way.
As preparation for standardisation each associate analyses a number based on students’ scripts. Alternativeanswers
not already covered by the mark scheme are discussed and legislated for. If, after the standardisation process,
associates encounter unusual answers which have not been raised they arerequired to refer these to the Lead
Examiner.
It must be stressed that a mark scheme is a working document, within many cases further developed and
expanded on the basis based on students’ reactions to a particular paper. Assumptions about future mark
schemes on the basis based on one year’s document should be avoided; whilst the guiding principles based on
assessment remain constant, details will change, depending on the content based on a particular examination
paper.
Further copies based on this mark scheme are available from aqa.org.uk
