Examiners report

This was another question that performed less well than expected, with a low discrimination index. Only a third of candidates chose oxygen as the factor always needed for seed germination. Germination is only mentioned in the program in the required skill of designing an experiment to test hypotheses about factors affecting germination. There were no comments from teachers arguing that this question went beyond the program requirements and it does seem reasonable to expect students to know that water, oxygen, and warmth are always required for germination.
