General Marking Guidance All candidates must receive the same treatment. Examiners must mark the firstcandidate in exactly the same way as they mark the last. Mark schemes should be applied positively. Candidates must be rewarded for whatthey have shown they can do rather than penalised for omissions. Examiners should mark according to the mark scheme not according to theirperception of where the grade boundaries may lie. There is no ceiling on achievement. All marks on the mark scheme should be usedappropriately. All the marks on the mark scheme are designed to be awarded. Examiners shouldalways 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 responseis not worthy of credit according to the mark scheme. Where some judgement is required, mark schemes will provide the principles bywhich marks will be awarded and exemplification may be limited. When examiners are in doubt regarding the application of the mark scheme to acandidate’s response, the team leader must be consulted. Crossed out work should be marked UNLESS the candidate has replaced it with analternative response. Mark schemes will indicate within the table where, and which strands of QWC, arebeing assessed. The strands are as follows:i) ensure that text is legible and that spelling, punctuation and grammar are accurateso that meaning is clearii) select and use a form and style of writing appropriate to purpose and to complexsubject matteriii) organise information clearly and coherently, using specialist vocabulary whenappropriate
Using the Mark SchemeExaminers should look for qualities to reward rather than faults to penalise. This does NOTmean giving credit for incorrect or inadequate answers, but it does mean allowing candidatesto be rewarded for answers showing correct application of principles and knowledge.Examiners should therefore read carefully and consider every response: even if it is not whatis expected it may be worthy of credit.The mark scheme gives examiners: an idea of the types of response expected how individual marks are to be awarded the total mark for each question examples of responses that should NOT receive credit./ means that the responses are alternatives and either answer should receive full credit.( ) means that a phrase/word is not essential for the award of the mark, but helps theexaminer to get the sense of the expected answer.Phrases/words in bold indicate that the meaning of the phrase or the actual word is essentialto the answer.ecf/TE/cq (error carried forward) means that a wrong answer given in an earlier part of aquestion is used correctly in answer to a later part of the same question.Candidates must make their meaning clear to the examiner to gain the mark. Make sure thatthe answer makes sense. Do not give credit for correct words/phrases which are put togetherin a meaningless manner. Answers must be in the correct context.Quality of Written CommunicationQuestions which involve the writing of continuous prose will expect candidates to: write legibly, with accurate use of spelling, grammar and punctuation in order to make themeaning clear select and use a form and style of writing appropriate to purpose and to complex subjectmatter organise information clearly and coherently, using specialist vocabulary when appropriate.Full marks will be awarded if the candidate has demonstrated the above abilities.Questions where QWC is likely to be particularly important are indicated (QWC) in the markscheme, but this does not preclude others.
