, 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 schemes will indicate within the table where, and which strands of
QWC, are being assessed. The strands are as follows:
i) ensure that text is legible and that spelling, punctuation and grammar are
EDEXCEL A LEVEL JUNE 2023 CHEMISTRY 9cho MARKSCHEME PAPER 2.pdf
accurate so that meaning is clear
ii) select and use a form and style of writing appropriate to purpose and to
complex subject matter
iii) organise information clearly and coherently, using specialist vocabulary
when appropriate
