MARK SCHEME

Maximum Mark: 75

Published

This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the

examination. It shows the basis on which Examiners were instructed to award marks. It does not indicate the

details of the discussions that took place at an Examiners’ meeting before marking began, which would have

considered the acceptability of alternative answers.

Mark schemes should be read in conjunction with the question paper and the Principal Examiner Report for

Teachers.

Cambridge International will not enter into discussions about these mark schemes.

Cambridge International is publishing the mark schemes for the October/November 2018 series for most

Cambridge IGCSETM, Cambridge International A and AS Level components and some Cambridge O Level

components.

Generic Marking Principles

These general marking principles must be applied by all examiners when marking candidate answers. They should be applied alongside the

specific content of the mark scheme or generic level descriptors for a question. Each question paper and mark scheme will also comply with these

marking principles.

GENERIC MARKING PRINCIPLE 1:

Marks must be awarded in line with:

• the specific content of the mark scheme or the generic level descriptors for the question

• the specific skills defined in the mark scheme or in the generic level descriptors for the question

• the standard of response required by a candidate as exemplified by the standardisation scripts.

GENERIC MARKING PRINCIPLE 2:

Marks awarded are always whole marks (not half marks, or other fractions).

GENERIC MARKING PRINCIPLE 3:

Marks must be awarded positively:

• marks are awarded for correct/valid answers, as defined in the mark scheme. However, credit is given for valid answers which go beyond the

scope of the syllabus and mark scheme, referring to your Team Leader as appropriate

• marks are awarded when candidates clearly demonstrate what they know and can do

• marks are not deducted for errors

• marks are not deducted for omissions

• answers should only be judged on the quality of spelling, punctuation and grammar when these features are specifically assessed by the

question as indicated by the mark scheme. The meaning, however, should be unambiguous.

GENERIC MARKING PRINCIPLE 4:

Rules must be applied consistently e.g. in situations where candidates have not followed instructions or in the application of generic level

descriptors.
