What examiners said
Most candidates correctly counted the number of ungerminated seeds and germinated seeds.
— Examiner report, May/June 2025, 0653/63 Q1(a)(i) (Cambridge)
Most candidates stated a suitable environmental condition for germination. A few candidates stated warmth as a condition. Careful reading of the question excluded this as a response, as it had already been mentioned.
— Examiner report, February/March 2024, 0653/32 Q7(c) (Cambridge)
Most candidates incorrectly selected option C. This option described pollination of flowering plants, not fertilisation.
— Examiner report, October/November 2023, 0653/12 Q11 (Cambridge)
