Mark Scheme Notes
•
Marks are of the following three types:
M
Method mark, awarded for a valid method applied to the problem. Method
marks are not lost for numerical errors, algebraic slips or errors in units.
However, it is not usually sufficient for a candidate just to indicate an intention
of using some method or just to quote a formula; the formula or idea must be
applied to the specific problem in hand, e.g. by substituting the relevant
quantities into the formula. Correct application of a formula without the formula
being quoted obviously earns the M mark and in some cases an M mark can
be implied from a correct answer.
A
Accuracy mark, awarded for a correct answer or intermediate step correctly
obtained. Accuracy marks cannot be given unless the associated method
mark is earned (or implied).
B
Mark for a correct result or statement independent of method marks.
•
When a part of a question has two or more "method" steps, the M marks are
generally independent unless the scheme specifically says otherwise; and similarly
when there are several B marks allocated. The notation DM or DB (or dep*) is used
to indicate that a particular M or B mark is dependent on an earlier M or B
(asterisked) mark in the scheme. When two or more steps are run together by the
candidate, the earlier marks are implied and full credit is given.
•
The symbol √
implies that the A or B mark indicated is allowed for work correctly
following on from previously incorrect results. Otherwise, A or B marks are given for
correct work only. A and B marks are not given for fortuitously "correct" answers or
results obtained from incorrect working.
•
Note:
B2 or A2 means that the candidate can earn 2 or 0.
B2, 1, 0 means that the candidate can earn anything from 0 to 2.
•
The following abbreviations may be used in a mark scheme or used on the scripts:
AG
Answer Given on the question paper (so extra checking is needed to
ensure that the detailed working leading to the result is valid)
BOD
Benefit of Doubt (allowed when the validity of a solution may not be
absolutely clear)
CAO
Correct Answer Only (emphasising that no "follow through" from a
previous error is allowed)
ISW
Ignore Subsequent Working
MR
Misread
PA
Premature Approximation (resulting in basically correct work that is
insufficiently accurate)
SOS
See Other Solution (the candidate makes a better attempt at the same
question)

Penalties
•
MR
±
1
A penalty of MR
±
1 is deducted from A or B marks when the data of a
question or part question are genuinely misread and the object and
difficulty of the question remain unaltered. In this case all A and B
marks
then become "follow through √ " marks. MR is not applied when the
candidate misreads his own figures – this is regarded as an error in
accuracy.
