Notes:
These questions have been retyped from the original sample/specimen
assessment materials and whilst every effort has been made to ensure there
are no errors, any that do appear are mine and not the exam board s (similarly
any errors I have corrected from the originals are also my corrections and not
theirs!).
Please also note that the layout in terms of fonts, answer lines and space given
to each question does not reflect the actual papers to save space.
These questions have been collated by me as the basis for a GCSE working
party set up by the GLOW maths hub - if you want to get involved please get
in touch. The objective is to provide support to fellow teachers and to give you
a flavour of how different topics “could” be examined. They should not be used
to form a decision as to which board to use. There is no guarantee that a topic
will or won’t appear in the “live” papers from a specific exam board or that
examination of a topic will be as shown in these questions.
