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.
