, MARK SCHEME – AS BIOLOGY – 7401/2 – JUNE
2022
Mark schemes are prepared by the Lead Assessment Writer and considered, together with
the relevant questions, by a panel of subject teachers. This mark scheme includes any
amendments made at the standardisation events which all associates participate in and is
the scheme which was used by them in this examination. The standardisation process
ensures that the mark scheme covers the students’ responses to questions and that every
associate understands and applies it in the same correct way.
As preparation for standardisation each associate analyses a number of students’ scripts.
Alternative answers 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 are required to refer these to the Lead Examiner.
It must be stressed that a mark scheme is a working document, in many cases further
developed and expanded on the basis of students’ reactions to a particular paper.
Assumptions about future mark schemes on the basis of one year’s document should be
avoided; whilst the guiding principles of assessment remain constant, details will change,
depending on the content of a particular examination paper.
Further copies of this mark scheme are available from aqa.org.uk
