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.

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.

My power was 70 watts and my heart rate was 80.
Then I pedalled faster, my heart rate reached 100 and my
power went to 120.
When my power was 170, my heart rate was 120.
I pedalled harder up to 220 watts and my heart rate was 140.
When I worked my hardest, the readings were 270 watts
and 160 beats per minute.
