,General Marking Guidance
All candidates must receive the same treatment. Examiners must
mark the first candidate in exactly the same way as they mark the
last.
Mark schemes should be applied positively. Candidates must be
rewarded for what they have shown they can do rather than
penalised for omissions.
Examiners should mark according to the mark scheme not according
to their perception of where the grade boundaries may lie.
There is no ceiling on achievement. All marks on the mark scheme
should be used appropriately.
All the marks on the mark scheme are designed to be awarded.
Examiners should always award full marks if deserved, i.e. if the
answer matches the mark scheme. Examiners should also be
prepared to award zero marks if the candidate’s response is not
worthy of credit according to the mark scheme.
Where some judgement is required, mark schemes will provide the
principles by which marks will be awarded and exemplification may
be limited.
When examiners are in doubt regarding the application of the mark
scheme to a candidate’s response, the team leader must be
consulted.
Crossed out work should be marked UNLESS the candidate has
replaced it with an alternative response.
, Mark scheme notes
Underlying principle
The mark scheme will clearly indicate the concept that is being
rewarded, backed up by examples. It is not a set of model answers.
1.Mark scheme format
1.1You will not see ‘wtte’ (words to that effect). Alternative correct
wording should be credited in every answer unless the MS has
specified specific words that must be present. Such words will be
indicated by underlining e.g. ‘resonance’
1.2Bold lower case will be used for emphasis e.g. ‘and’ when two pieces of
information are needed for 1 mark.
1.3Round brackets ( ) indicate words that are not essential e.g.
“(hence) distance is increased”.
1.4Square brackets [ ] indicate advice to examiners or examples e.g. [Do
not accept gravity] [ecf].
2.Unit error penalties
2.1A separate mark is not usually given for a unit but a missing or
incorrect unit will normally mean that the final calculation mark will not
be awarded.
2.2This does not apply in ‘show that’ questions or in any other question
where the units to be used have been given, for example in a
spreadsheet.
2.3The mark will not be awarded for the same missing or incorrect unit
only once within one clip in epen.
2.4Occasionally, it may be decided not to insist on a unit e.g the candidate
may be calculating the gradient of a graph, resulting in a unit that is
not one that should be known and is complex.
2.5The mark scheme will indicate if no unit error is to be applied by
means of [no ue].
3.Significant figures
3.1Use of too many significant figures in the theory questions will not be
prevent a mark being awarded if the answer given rounds to the
answer in the MS.
3.2Too few significant figures will mean that the final mark cannot be
awarded in ‘show that’ questions where one more significant figure
than the value in the question is needed for the candidate to
demonstrate the validity of the given answer.
3.3The use of one significant figure might be inappropriate in the context
of the question e.g. reading a value off a graph. If this is the case,
there will be a clear indication in the MS.
3.4The use of g = 10 m s-2 or 10 N kg-1 instead of 9.81 m s-2 or 9.81 N kg-1
will mean that one mark will not be awarded. (but not more than once
per clip). Accept 9.8 m s-2 or 9.8 N kg-1
3.5In questions assessing practical skills, a specific number of significant
figures will be required e.g. determining a constant from the gradient of
