Mark Scheme for June 2023
,Ab
OCR (Oxford Cambridge and RSA) is a leading UK awarding body, providing a wide
range of qualifications to meet the needs of candidates of all ages and abilities. OCR
qualifications include AS/A Levels, Diplomas, GCSEs, Cambridge Nationals,
Cambridge Technicals, Functional Skills, Key Skills, Entry Level qualifications, NVQs
and vocational qualifications in areas such as IT, business, languages,
teaching/training, administration and secretarial skills.
It is also responsible for developing new specifications to meet national
requirements and the needs of students and teachers. OCR is a not-for-profit
organisation; any surplus made is invested back into the establishment to help
towards the development of qualifications and support, which keep pace with the
changing needs of today’s society.
This mark scheme is published as an aid to teachers and students, to indicate the
requirements of the examination. It shows the basis on which marks were awarded
by examiners. It does not indicate the details of the discussions which took place at
an examiners’ meeting before marking commenced.
All examiners are instructed that alternative correct answers and unexpected
approaches in candidates’ scripts must be given marks that fairly reflect the
relevant knowledge and skills demonstrated.
Mark schemes should be read in conjunction with the published question papers
and the report on the examination.

the RM Cambridge Assessment Support Portal http://www.rm.com/support/ca
3. Log-in to RM assessor and mark the required number of practice responses (“scripts”) and the number of required standardisation
responses.
YOU MUST MARK 5 PRACTICE AND 10 STANDARDISATION RESPONSES BEFORE YOU CAN BE APPROVED TO MARK LIVE SCRIPTS.
MARKING
1. Mark strictly to the mark scheme.
2. Marks awarded must relate directly to the marking criteria.
3. The schedule of dates is very important. It is essential that you meet the 50% and 100% deadlines. If you experience
problems, you must contact your Team Leader (Supervisor) without delay.
4. If you are in any doubt about applying the mark scheme, consult your Team Leader by telephone or the RM assessor messaging
system, or by email.
5. Crossed Out Responses
Where a candidate has crossed out a response and provided a clear alternative then the crossed-out response is not marked. Where
no alternative response has been provided, examiners may give candidates the benefit of the doubt and mark the crossed-out
response where legible.
Contradictory Responses
When a candidate provides contradictory responses, then no mark should be awarded, even if one of the answers is correct.
, Short Answer Questions (requiring only a list by way of a response, usually worth only one mark per response)
Where candidates are required to provide a set number of short answer responses then only the set number of responses should be
marked. The response space should be marked from left to right on each line and then line by line until the required number of
responses have been considered. The remaining responses should not then be marked. Examiners will have to apply judgement as
to whether a ‘second response’ on a line is a development
