What examiners said
Most candidates gained two marks for identifying the description of anaerobic respiration. Many gained all three marks.
— Examiner report, February/March 2025, 0610/32 Q3(c)(i) (Cambridge)
Only a minority of candidates gave the correct response. It is important for candidates to work carefully and methodically through the information provided. Successful candidates evaluated each statement in turn to deduce that all three conclusions were correct.
— Examiner report, May/June 2021, 0610/11 Q29 (Cambridge)
Many candidates realised that oxygen must be stopped from entering the jar when alcohol is being made.
— Examiner report, May/June 2021, 0610/33 Q5(b)(iii) (Cambridge)
