Mark Scheme for June 2023
,A level 1
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.
