What examiners said
Most candidates gain full marks here although some named cells rather than stating the appropriate letter. Letters A and D were often swapped around.
— Examiner report, May/June 2025, 0970/31 Q1(a) (Cambridge)
Most knew the nucleus contains genetic information and/or DNA. Although most knew the correct answer some missed marks by poorly expressing themselves or by adding incorrect information, such as the nucleus controlling what enters and leaves the cell or storing nutrients for example.
— Examiner report, May/June 2025, 0970/31 Q1(b)(i) (Cambridge)
Most were awarded at least one mark, usually for cytoplasm or cell membrane. Incorrect answers included cell walls and chloroplasts.
