(c) square root ( ) and cube root ( 3 ) functions; and

(d) value of Pi (π). - The following guidelines are to be adhered to in the use of calculators in national examinations.

(a) The calculator must be silent, with a visual display only.

external storage media, e.g. cards, tapes, and plug-in modules, are allowed.

(e) No calculators with wireless communication capability with other machines, e.g. infra-red

communication capability, are allowed.

(f) Any enclosed instruction leaflets containing any mathematical formula, conversion table or

instructions are strictly prohibited, and must not be taken into the examination venue. Any such

information on the calculator that cannot be removed must be securely covered.

(g) The original model number and brand must be indicated clearly on the calculator for verification

purposes.

(j) No programmable calculators are allowed.

(k) No calculators with permanent features of a programmed kind are allowed,

e.g. calculators capable of numerical integration and/or numerical differentiation. - Graphing calculators are allowed for use ONLY in subjects examined at H1, H2 and H3 Levels of the GCE

A-Level Curriculum. Candidates are to note the following:

(a) It is the candidates’ responsibility to clear any information and/or programs stored in the graphing

examination.

(c) No calculators with built-in symbolic algebra manipulations, symbolic differentiation or integration

are allowed. - The use of any calculator with unacceptable features or for retrieval of information/programs during the

examinations is an infringement of the regulations. - All previously approved calculators are allowed in the national examinations. The Singapore

Examinations and Assessment Board reserves the right to withdraw the approval for these calculators in
