External AssessmentModule Tests (papers 8 13)

ResitsStudents may resit any module test once only and the better result will count towards the final award.The shelf-life of individual modules is limited only by the shelf-life of the specification. The fullqualification may be retaken more than once.The papersModule tests will be combined question/answer books containing both shorter and longer questions.

Module 1 (examination papers 8, 9 and 10) will be timetabled in one session and module 2(examination papers 11, 12 and 13) in another.

The focus of assessment for module 1 in each tier will be the material identified in the stage 1 contentfor that tier.

The focus of assessment for module 2 in each tier will be the material identified in the stage 2 contentfor that tier, but knowledge of the content in the associated stage 1 will be assumed.

Section A in each module test will be a non-calculator section. In this section calculators, slide rules,logarithm tables and all other calculating aids are forbidden.

Module test section A may test any topic in the subject content appropriate to the stage and tier ofentry, except those that expressly require the use of a calculator.

Module test section B may test any topic in the subject content appropriate to the stage and tier ofentry, except those that expressly prohibit the use of a calculator.

Each module test will carry a maximum mark of 38 (equally divided between sections A and B).

Whilst each module test will assess the full range of grades at each tier, the emphasis will be on thelower grades available for the tier of entry.

Examination papers 14 19

Examination papers 14 19 will be combined question/answer books containing both shorter andlonger questions.

Examination papers 14, 16 and 18 will be timetabled in one session and examination papers 15, 17and 19 in another.

Examination papers 14, 16 and 18 will be non-calculator papers. In these papers calculators, sliderules, logarithm tables and all other calculating aids are forbidden.

The non-calculator examination papers may test any topic in the subject content appropriate to the tierof entry, except those that expressly require the use of a calculator.

The with-calculator examination papers may test any topic in the subject content appropriate to thetier of entry, except those that expressly prohibit the use of a calculator.

Each examination paper will carry a maximum mark of 62.

There will be two parallel examination papers for each tier.

Whilst each examination paper will assess the full range of grades at each tier, there will be anemphasis on the higher grades available for the tier of entry.


The examination papers for each tier will assess the full range of content given in the specification forthat tier. However there will be a slight emphasis on the material identified in stage 3 of the relevanttier.

There will be common questions across examination papers to aid standardisation and comparabilityof awards between tiers.

General issues relating to both module tests and examination papers

There will be a number of questions demanding the unprompted solution of multi-step problems.

There will be a number of questions requiring the use of manipulative algebra.

Taken together the module tests and examination papers in the higher and intermediate tiers will offera balanced assessment across the grades available in the tier.

In the foundation tier, about one third of the marks awarded across the module tests and examinationpapers will be allocated to grade G material and the remaining marks will be balanced across the othergrades.

Questions on the intermediate tier module tests and examination papers will assume knowledge fromthe foundation tier. However, material related to grades below the range of the tier will not be thefocus of assessment.

Questions on the higher tier module tests and examination papers will assume knowledge from theintermediate tier. However, material related to grades below the range of the tier will not be the focusof assessment.

Diagrams will not necessarily be drawn to scale and measurements should not be taken from diagramsunless instructions to this effect are given.

Each candidate may be required to use mathematical instruments e.g. pair of compasses, ruler,protractor.

Formulae sheets will be provided for foundation, intermediate and higher tiers.

Calculators

Candidates will be expected to have access to a suitable electronic calculator for all the modular testsand examination papers 15, 17 and 19.

The electronic calculator to be used by candidates attempting foundation tier module tests andexamination paper 15 should have, as a minimum, the following functions:

=================+, , , , x 2, x, memory, brackets, xy, yx1

The electronic calculator to be used by candidates attempting intermediate and higher tier moduletests and examination papers 17 and 19 should have, as a minimum, the following functions:

+, , , , x 2, x, memory, constant function, brackets, xy, yx1

Calculators which are not permitted in any paper include calculators such as Texas TI-89, TI-92,Casio cfx-9970G, Hewlett Packard HP 48G, Casio C-300. (NB There are almost certainly others thatare not permitted.)

g) change the subject of a formula find x given y = mx + c

generate a formula find the perimeter of a rectangle given its areaA and the length l of one side

find the inverse of simple rules, derivingexpressions



Contents Examples

Simultaneous linear equations

j) solve simple linear inequalities in onevariable, and represent the solution set on anumber line

26 + n > 4n 7

show 3 < x 4 on a number line

Numerical methods

m) use systematic trial andimprovement to find approximate solutionsof equations where there is no simpleanalytical method of solving them

solve x3 x = 900 to 1 decimal placex3 + x = 12 to 2 decimal places




b) plot graphs of functions in which y is givenexplicitly in terms of x (as in y = 2x + 3), orimplicitly (as in x + y = 7)

y = ax + b where b is an integer, a is a fractionor an integer

Interpreting graphical information

d) construct linear functions and plot thecorresponding graphs arising from real-lifeproblems

discuss and interpret graphs modelling realsituations

distance-time graph for a particle moving withconstant speed, the velocity-time graph for aparticle moving with constant acceleration

travel graphs, conversion graphs

the depth of water in a container as it empties

Quadratic functions

e) generate points and plot graphs ofsimple quadratic functions, then moregeneral quadratic functions

y = x2, y = 3x2 + 4y = x2 2x + 1y = ax2 + bx + c




Contents Examples




f) understand, recall and usePythagoras theorem in 2-D problems

calculate the height (altitude) of an isoscelestriangle given the lengths of all three sides

g) understand, recall and usetrigonometrical relationships in right-angledtriangles, and use these to solve problems,including those involving bearings

may involve angles of elevation and depression

right-angled triangles in 2-D only


h) understand that the tangent at anypoint on a circle is perpendicular to theradius at that point

understand and use the fact that tangentsfrom an external point are equal in length

understand that inscribed regular polygons canbe constructed by equal division of a circle

two tangents to a circle from an external pointproduce a situation that is symmetrical




a) understand that translations arespecified by giving a distance and direction (ora vector), and enlargements by a centre and apositive scale factor

a translation by the vector

32

describe transformations

describe combinations of transformations


c) recognise, visualise and constructenlargements of objects

from a given centre



Contents Examples

understand from this that any two circles andany two squares are mathematically similar,while, in general, two rectangles are not, thenuse positive fractional scale factors

enlargement scale factor 31 , 2 2

1

d) recognise that enlargements preserveangle but not length

identify the scale factor of an enlargement asthe ratio of the lengths of any twocorresponding line segments

understand the implications of enlargement forperimeter

use and interpret maps and scale draw
