MARK SCHEME
Maximum Mark: 40
Published
This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the
examination. It shows the basis on which Examiners were instructed to award marks. It does not indicate the
details of the discussions that took place at an Examiners’ meeting before marking began, which would have
considered the acceptability of alternative answers.
Mark schemes should be read in conjunction with the question paper and the Principal Examiner Report for
Teachers.
Cambridge International will not enter into discussions about these mark schemes.
Cambridge International is publishing the mark schemes for the May/June 2023 series for most
Cambridge IGCSE, Cambridge International A and AS Level and Cambridge Pre-U components, and some
Cambridge O Level components.
This document consists of 5 printed pages.

Cambridge IGCSE – Mark Scheme
PUBLISHED
May/June 2023
Generic Marking Principles
These general marking principles must be applied by all examiners when marking candidate answers. They
should be applied alongside the specific content of the mark scheme or generic level descriptors for a question.
Each question paper and mark scheme will also comply with these marking principles.
GENERIC MARKING PRINCIPLE 1:
Marks must be awarded in line with:



the specific content of the mark scheme or the generic level descriptors for the question
the specific skills defined in the mark scheme or in the generic level descriptors for the question
the standard of response required by a candidate as exemplified by the standardisation scripts.
GENERIC MARKING PRINCIPLE 2:
Marks awarded are always whole marks (not half marks, or other fractions).
GENERIC MARKING PRINCIPLE 3:
Marks must be awarded positively:





marks are awarded for correct/valid answers, as defined in the mark scheme. However, credit is given for
valid answers which go beyond the scope of the syllabus and mark scheme, referring to your Team
Leader as appropriate
marks are awarded when candidates clearly demonstrate what they know and can do
marks are not deducted for errors
marks are not deducted for omissions
answers should only be judged on the quality of spelling, punctuation and grammar when these features
are specifically assessed by the question as indicated by the mark scheme. The meaning, however,
should be unambiguous.
GENERIC MARKING PRINCIPLE 4:
Rules must be applied consistently, e.g. in situations where candidates have not followed instructions or in
the application of generic level descriptors.
GENERIC MARKING PRINCIPLE 5:
Marks should be awarded using the full range of marks defined in the mark scheme for the question
(however; the use of the full mark range may be limited according to the quality of the candidate responses
seen).
GENERIC MARKING PRINCIPLE 6:
Marks awarded are based solely on the requirements as defined in the mark scheme. Marks should not be
awarded with grade thresholds or grade descriptors in mind.

Maths-Specific Marking Principles
1
Unless a particular method has been specified in the question, full marks may be awarded for any correct
method. However, if a calculation is required then no marks will be awarded for a scale drawing.
2
Unless specified in the question, answers may be given as fractions, decimals or in standard form. Ignore
superfluous zeros, provided that the degree of accuracy is not affected.
3
Allow alternative conventions for notation if used consistently throughout the paper, e.g. commas being
used as decimal points.
4
Unless otherwise indicated, marks once gained cannot subsequently be lost, e.g. wrong working
following a correct form of answer is ignored (isw).
5
Where a candidate has misread a number in the question and used that value consistently throughout,
provided that number does not alter the difficulty or the method required, award all marks earned and
deduct just 1 mark for the misread.
6
Recovery within working is allowed, e.g. a notation error in the working where the following line of
working makes the candidate’s intent clear.
MARK SCHEME NOTES
The following notes are intended to aid interpretation of mark schemes in general, but individual mark schemes
may include marks awarded for specific reasons outside the scope of these notes.
Types of mark
M
Method marks, awarded for a valid method applied to the problem.
A
Accuracy mark, awarded for a correct answer or intermediate step correctly obtained. For accuracy
marks to be given, the associated Method mark must be earned or implied.
B
Mark for a correct result or statement independent of Method marks.
When a part of a question has two or more ‘method’ steps, the M marks are in principle independent unless the
scheme specifically says otherwise; and similarly where there are several B marks allocated. The notation ‘dep’
is used to indicate that a particular M or B mark is dependent on an earlier mark in the scheme.
