Paper 2
Mark scheme
Mark schemes are prepared by the Lead Assessment Writer and considered,
together with the relevant questions, by a panel of subject teachers. This mark
scheme includes any amendments made at the standardisation events which
all associates participate in and is the scheme which was used by them in this
examination. The standardisation process ensures that the mark scheme
covers the students’ responses to questions and that every associate
understands and applies it in the same correct way.
As preparation for standardisation each associate analyses a number of
students’ scripts. Alternativeanswers not already covered by the mark scheme
are discussed and legislated for. If, after the standardisation process,
associates encounter unusual answers which have not been raised they are
required to refer these to the Lead Assessment Writer.
It must be stressed that a mark scheme is a working document, in many
cases further developed and expanded on the basis of students’ reactions to a
particular paper. Assumptions about future mark schemes on the basis of one
year’s document should be avoided; whilst the guiding principles of
assessment remain constant, details will change, depending on the content of
a particular examinationpaper.

, Physics - Mark scheme instructions to examiners
• General
The mark scheme for each question shows:
• the marks available for each part of the question
• the total marks available for the question
• the typical answer or answers which are expected
• extra information to help the Examiner make his or her judgement
and help to delineate what is acceptable or not worthy of credit or,
in discursive answers, to give an overview of the area in which a
mark or marks may be awarded.
The extra information is aligned to the appropriate answer in the left-
hand part of the markscheme and should only be applied to that item
in the mark scheme.
At the beginning of a part of a question a reminder may be given, for
example: where consequential marking needs to be considered in a
calculation; or the answer may be on thediagram or at a different place
on the script.
In general the right-hand side of the mark scheme is there to provide
those extra details whichconfuse the main part of the mark scheme yet
may be helpful in ensuring that marking is straightforward and
consistent.
• Emboldening
• In a list of acceptable answers where more than one mark is
available ‘any two from’ isused, with the number of marks
emboldened. Each of the following bullet points is a potential
mark.
• A bold and is used to indicate that both parts of the answer
are required to award the mark.
• Alternative answers acceptable for a mark are indicated by the
use of or. Different termsin the mark scheme are shown by a /
; eg allow smooth / free movement.
• Marking points
• Marking of lists
This applies to questions requiring a set number of responses,
but for which candidates have provided extra responses. The
general principle to be followed in such a situation is that ‘right +
wrong = wrong’.
Each error / contradiction negates each correct response. So, if
the number of errors /contradictions equals or exceeds the
number of marks available for the question, no marks can be
awarded.
