Key examiner messages
Top priorities from the principal examiner before you revise
The May/June 2023 series for Cambridge IGCSE Co-ordinated Sciences (0654) showcased a standard distribution of marks across Biology, Chemistry, and Physics.
While candidate recall of fundamental concepts was solid, significant hurdles remained in the precise application of kinetic theory, quantitative conversions, and the articulation of specific physical mechanisms such as vasodilation and wave characteristics.
