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.
