What examiners said

Candidates had to specify that it is the coronary arteries that becomes blocked causing CHD. Simply referring to blockage of arteries or blood vessels was insufficient.

— Examiner report, May/June 2023, 0653/43 Q7(b)(i) (Cambridge)

There was a long list of acceptable risk factors for CHD and many candidates were awarded full credit. One suggestion that did not attract credit was the vague idea of poor diet.

— Examiner report, May/June 2023, 0653/43 Q7(b)(ii) (Cambridge)

Candidates usually stated two correct risk factors. Some candidates stated only “exercise” rather than “lack of exercise” or “no exercise”.

— Examiner report, October/November 2022, 0653/43 Q4(a)(ii) (Cambridge)
