, General marking guidance
These notes offer general guidance, but the specific notes for examiners appertaining to
individual questions take precedence.
1 All candidates must receive the same treatment. Examiners must mark the last
candidate in exactly the same way as they mark the first.
Where some judgement is required, mark schemes will provide the principles by
which marks will be awarded; exemplification/indicative content will not be
exhaustive. When examiners are in doubt regarding the application of the mark
scheme to a candidate’s response, the response should be sent to review.
2 All the marks on the mark scheme are designed to be awarded; mark schemes
should be applied positively. Examiners should also be prepared to award zero
marks if the candidate’s response is not worthy of credit according to the mark
scheme. If there is a wrong answer (or no answer) indicated on the answer line
always check the working in the body of the script (and on any diagrams), and
award any marks appropriate from the mark scheme.
Questions where working is not required: In general, the correct answer
should be given full marks.
Questions that specifically require working: In general, candidates who do
not show working on this type of question will get no marks – full details will be
given in the mark scheme for each individual question.
3 Crossed out work
This should be marked unless the candidate has replaced it with an alternative
response.
4 Choice of method
If there is a choice of methods shown, mark the method that leads to the answer
given on the answer line.
If no answer appears on the answer line then mark both methods as far as they
are identical and award these marks.
5 Incorrect method
If it is clear from the working that the “correct” answer has been obtained from
incorrect working, award 0 marks.
6 Follow through marks
Follow through marks which involve a single stage calculation can be awarded
without working as you can check the answer, but if ambiguous do not award.
Follow through marks which involve more than one stage of calculation can only
be awarded on sight of the relevant working, even if it appears obvious that there
is only one way you could get the answer given.
7 Ignoring subsequent work
It is appropriate to ignore subsequent work when the additional work does not
change the answer in a way that is inappropriate for the question or its context.
(eg an incorrectly cancelled fraction when the unsimplified fraction would gain full
marks).
It is not appropriate to ignore subsequent work when the additional work
essentially makes the answer incorrect (eg incorrect algebraic simplification).
