OCR AS/A Level in Mathematics
B (MEI) and OCR AS/A Level in
Further Mathematics B (MEI) for
teaching from 2017
From 2017, AS and A level Mathematics and
Further Mathematics are required to have a
greater emphasis on modelling, problem solving,
reasoning and integration of technology, and
statistics will have a new focus on interpretation
of data. These are features that MEI has been
promoting for many years.
What’s so special about these
› Support
We offer exceptional support for
teachers and students including
textbooks, our Integral online
teaching and learning resources,
professional development and access
to experts to answer your questions
› The best possible motives
From its first A level examination in 1967, to its
present A level specification, MEI has produced
coherent and innovative syllabuses. We are
continuing this tradition with the new OCR(MEI)
AS and A level specifications.
MEI is a registered charity; our vision
is to make a real difference to people’s
lives by improving the quality of
mathematics education
