These sample assessment materials have been developed to support these qualifications and will be used as the benchmark to develop the assessment students will take. 1 Pearson edexcel INTERNATIONAL ADVANCED Subsidiary/ ADVANCED LEVEL in CHEMISTRY Sample Assessment Materials Issue 1 September 2017 Pearson Education Limited 20172 Pearson edexcel INTERNATIONAL ADVANCED Subsidiary/ ADVANCED LEVEL in CHEMISTRY Sample Assessment Materials Issue 1 September 2017 Pearson Education Limited 2017 General marking guidance All candidates must receive the same treatment. Examiners must mark the last candidate in exactly the same way as they mark the first.

5 Mark schemes should be applied positively. Candidates must be rewarded for what they have shown they can do rather than be penalised for omissions. Examiners should mark according to the mark scheme not according to their perception of where the grade boundaries may lie. All the marks on the mark scheme are designed to be awarded. Examiners should always award full marks if deserved, 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/indicative content will not be exhaustive. However different examples of responses will be provided at standardisation. When examiners are in doubt regarding the application of the mark scheme to a candidate s response, a senior examiner must be consulted before a mark is given.

6 Crossed-out work should be marked unless the candidate has replaced it with an alternative response. Using the Mark Scheme Examiners should look for qualities to reward rather than faults to penalise. This does NOT mean giving credit for incorrect or inadequate answers, but it does mean allowing candidates to 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 what is 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 the examiner to get the sense of the expected answer.

7 Phrases/words in bold indicate that the meaning of the phrase or the actual word is essential to the answer. ecf/TE/cq (error carried forward) means that a wrong answer given in an earlier part of a question 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 that the answer makes sense. Do not give credit for correct words/phrases which are put together in a meaningless manner. Answers must be in the correct context. 3 Pearson edexcel INTERNATIONAL ADVANCED Subsidiary/ ADVANCED LEVEL in CHEMISTRY Sample Assessment Materials Issue 1 September 2017 Pearson Education Limited 2017 Centre NumberCandidate NumberWrite your name hereSurnameOther namesTotal MarksPaper Reference*S58309A0124*S58309A 2018 Pearson Education over Instructions Use black ink or black ball-point pen.
