7. Double Award Unit 2Foundation tier only questionsQUESTION 3 – chromatographyPart (c) well donePart (d) – not attempted by 1 in 4; poor knowledge
8. Double Award Unit 2Foundation tier only questionsQUESTION 4 – plate tectonicsFF 85Rounding 0.895 to 0.89 penalised
9. Double Award Unit 2Foundation tier only questionsQUESTION 5 – metals (PISA-style)FF 7Would more have gained a mark if we’d asked for the formula of sodium sulfate?
10. Double Award Unit 2Foundation tier only questionsQUESTION 6 – fluoridation of water (QER)FF 19Surprisingly poorly answered, weak discussion of reasons to oppose fluoridation
11. Double Award Unit 2Foundation tier only questionsQUESTION 7 – reaction rateFF 45Many used a mass rather than a decrease in mass
12. Double Award Unit 2Common questionsQUESTION 8/1 – elements and Group 1FF 56; 83FF 26; 46
13. Double Award Unit 2Common questionsQUESTION 9/2 – the atmospherePart (c) 70% attempt rate on FT; FF 12FF 55 on HTOverall FF 14 for question 9 on FT; 41 on HT
14. Double Award Unit 2Higher tier only questionsQUESTION 3 – ion testsFF 20Surprisingly poor knowledge of simple tests
15. Double Award Unit 2 Higher tier only questionsQUESTION 4 – solubilityFF 6Understanding of practical work
16. QUESTION 4 – solubilityDouble Award Unit 2 Higher tier only questionsFF 6No knowledge of method given in Guidance for Teachers
17. QUESTION 5 – percentage by massDouble Award Unit 2 Higher tier only questionsFF 21Unable to rearrange equation
18. QUESTION 6 – hard water (QER)Double Award Unit 2 Higher tier only questionsFF 17Candidates often answered their own similar question
19. QUESTION 7 – Group 7Double Award Unit 2 Higher tier only questionsFF 9; little idea of this difficult area of the specification; incorrect formulae in equationFF 19; most common mark was for finding relative mass on 2Fe and 3Cl2
