, MARK SCHEME – A-LEVEL BIOLOGY – 7402/1 – 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.

Mark scheme instructions to examiners
1. General
The mark scheme for each question shows:
• the marks available for each part of the question
• the total marks available for the question
• the typical answer or answers which are expected
• extra information to help the examiner make his or her judgement and help to delineate what is
acceptable or not worthy of credit or, in discursive answers, to give an overview of the area in which a
mark or marks may be awarded.
The extra information in the ‘Comments’ column is aligned to the appropriate answer in the left- hand
part of the mark scheme and should only be applied to that item in the mark scheme.
At the beginning of a part of a question a reminder may be given, for example: where consequential
marking needs to be considered in a calculation; or the answer may be on the diagram or at a different
place on the script.
In general the right-hand side of the mark scheme is there to provide those extra details which confuse
the main part of the mark scheme yet may be helpful in ensuring that marking is straightforward and
consistent.
2. Emboldening
2.1 In a list of acceptable answers where more than one mark is available ‘any two from’ is used,
with the number of marks emboldened. Each of the following bullet points is a potential mark.
2.2 A bold and is used to indicate that both parts of the answer are required to award the mark.
2.3 Alternative answers acceptable for the same mark are indicated by the use of OR. Different
terms in the mark scheme are shown by a / ; eg allow smooth / free movement.
3. Marking points
3.1 Marking of lists
This applies to questions requiring a set number of responses, but for which students have
provided extra responses. The general principle to be followed in such a situation is that ‘right +
wrong = wrong’.
Each error / contradiction negates each correct response. So, if the number of errors /
contradictions equals or exceeds the number of marks available for the question, no marks can
be awarded.
However, responses considered to be neutral (often prefaced by ‘Ignore’ in the
‘Comments’ column of the mark scheme) are not penalised.
