MARK SCHEME

IMPORTANT NOTICE
Mark Schemes have been issued on the basis of one copy per Assistant examiner and two copies per Team
Leader.
Published
This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the
examination. It shows the basis on which Markers were instructed to award marks. It does not indicate the
details of the discussions that took place at a Markers’ meeting before marking began, which would have
considered the acceptability of alternative answers.
Mark schemes should be read in conjunction with the question paper and the Principal Examiner Report for
Teachers.
Cambridge will not enter into discussions about these mark schemes.
This document consists of 13 printed pages and 1 blank page.
