Mark Scheme for June 2024
Oxford Cambridge and RSA Examinations
,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.

5. Work crossed out:
a. where a candidate crosses out an answer and provides an alternative response, the crossed out response is not marked and gains no
marks
b. if a candidate crosses out an answer to a whole question and makes no second attempt, and if the inclusion of the answer does not
cause a rubric infringement, the assessor should attempt to mark the crossed out answer and award marks appropriately.
6. Always check the pages (and additional objects if present) at the end of the response in case any answers have been continued there. If the
candidate has continued an answer there then add a tick to confirm that the work has been seen.
7. There is a NR (No Response) option. Award NR (No Response)
- if there is nothing written at all in the answer space
- OR if there is a comment which does not in any way relate to the question (e.g. „can‟t do‟, „don‟t know‟)
- OR if there is a mark (e.g. a dash, a question mark) which isn‟t an attempt at the question.
Note: Award 0 marks – for an attempt that earns no credit (including copying out the question).
8. The RM Assessor comments box is used by your Team Leader to explain the marking of the practice responses. Please refer to these
comments when checking your practice responses. Do not use the comments box for any other reason.
If you have any questions or comments for your Team Leader, use the phone, the RM Assessor messaging system, or email.
9. Assistant Examiners will send a brief report on the performance of candidates to their Team Leader (Supervisor) via email by the end of the
marking period. The report should contain notes on particular strengths displayed as well as common errors or weaknesses. Constructive
criticism of the question paper/mark scheme is also appreciated.
