Cambridge International aS & a level Mathematics 9709 syllabus. Introduction
Syllabus for examination in 2019.

Why Cambridge International AS & A Levels?
Cambridge International AS & A Levels are international in outlook, but retain a local relevance.
The syllabuses provide opportunities for contextualised learning and the content has been created
to suit a wide variety of schools, avoid cultural bias and develop essential lifelong skills, including
creative thinking and problem-solving.
Our aim is to balance knowledge, understanding and skills in our qualiications to enable students to become

effective learners and to provide a solid foundation for their continuing educational journey. Cambridge
International AS & A Levels give learners building blocks for an individualised curriculum that develops their
knowledge, understanding and skills.
Cambridge International AS & A Level curricula are lexible. It is possible to offer almost any combination
from a wide range of subjects. Cambridge International A Level is typically a two-year course, and
Cambridge International AS Level is typically one year. Some subjects can be started as a Cambridge
International AS Level and extended to a Cambridge International A Level.
There are three possible assessment approaches for Cambridge International AS & A Level:
Option two

Option three

(remainder of A Level)

Cambridge International
aS level

Cambridge International
aS level


(standalone AS)

(AS is irst half of A Level)

Learners take the Cambridge
International AS Level only. The
syllabus content for Cambridge
International AS Level is half
of a Cambridge International
A Level programme.

Learners take the Cambridge
International AS Level in Year 1 and
in Year 2 complete the Cambridge
International A Level.

Cambridge
International
a level


Year 1

Option one

Year 2

Cambridge International

Learners take all papers of the
Cambridge International A Level course
in the same examination series, usually
at the end of the second year of study.

Every year thousands of learners with Cambridge International AS & A Levels gain places at leading
universities worldwide. Cambridge International AS & A Levels are accepted and valued by top
universities around the world including those in the UK, US (including Ivy League universities), European
nations, Australia, Canada and New Zealand. Learners should check the university website for speciic
entry requirements before applying.
Did you know?

In some countries universities accept Cambridge International AS Levels in their own right as
qualiications counting towards entry to courses in the same or other related subjects. Many learners
who take Cambridge International AS Levels also choose to progress to Cambridge International
A Level.

Cambridge International aS & a level Mathematics 9709 syllabus. Introduction
Syllabus for examination in 2019.

Why Cambridge International AS & A Level Mathematics?
about the syllabus
Cambridge International AS & A Level Mathematics is accepted by universities and employers as proof of

mathematical knowledge and understanding. Successful candidates gain lifelong skills, including:
• a deeper understanding of mathematical principles
• the further development of mathematical skills including the use of applications of mathematics in the
context of everyday situations and in other subjects that they may be studying
• the ability to analyse problems logically, recognising when and how a situation may be represented
mathematically
• the use of mathematics as a means of communication
• a solid foundation for further study.
The syllabus allows Centres lexibility to choose from three different routes to AS Level Mathematics – Pure
Mathematics only or Pure Mathematics and Mechanics or Pure Mathematics and Probability & Statistics.
Centres can choose from three different routes to Cambridge International A Level Mathematics depending
on the choice of Mechanics, or Probability & Statistics, or both, in the broad area of ‘applications’.
Guided learning hours
Guided learning hours give an indication of the amount of contact time teachers need to have with learners
to deliver a particular course. Our syllabuses are designed around 180 guided learning hours for Cambridge
International AS Level, and around 360 guided learning hours for Cambridge International A Level.
These igures are for guidance only. The number of hours needed to gain the qualiication may vary
depending on local practice and the learners’ previous experience of the subject.
Prior learning
We recommend that learners who are beginning this course should have previously completed a Cambridge

O Level or Cambridge IGCSE® course in Mathematics or the equivalent
Progression
Cambridge International A Level Mathematics provides a suitable foundation for the study of Mathematics
or related courses in higher education.
Cambridge International AS Level Mathematics is the irst half of Cambridge International A Level
Mathematics. Depending on local university entrance requirements, the qualiication may permit or assist
progression directly to university courses in Mathematics or some other subjects.
We recommend learners check the Cambridge recognitions database and the university websites to ind the
most up-to-date entry requirements for courses they wish to study.

Question papers
There is no choice of questions in any of the question papers and questions will be arranged approximately
in order of increasing mark allocations.
It is expected that candidates will have a calculator with standard ‘scientiic’ functions available for use
for all papers in the examination. Computers, graphical calculators and calculators capable of algebraic
manipulation are not permitted.
A list of formulae and tables of the normal distribution (MF9) is supplied for the use of candidates in the
examination. Details of the items in this list are given for reference in section 4.

Relationships between units
Units P2, M2, S2 are sequential to units P1, M1, S1 respectively, and the later unit in each subject area may
not be used for certiication unless the corresponding earlier unit is being (or has already been) used.
Unit P3 is also sequential to unit P1, and may not be used for certiication unless P1 is being (or has already
been) used. The subject content of unit P2 is a subset of the subject content of unit P3; otherwise, the
subject content for different units does not overlap, although later units in each subject area assume
knowledge of the earlier units.

Availability
This syllabus is examined in the June and November examination series. This syllabus is also available for
examination in March for India only.
This syllabus is available to private candidates.
Detailed timetables are available from www.cie.org.uk/timetables

Combining this with other syllabuses
Candidates can combine this syllabus in an examination series with any other Cambridge syllabus, except:
