- As an expert examiner, there is nothing more painful than watching a student who clearly understands a concept lose 10% or more of their total marks due to sloppy execution. In Cambridge IGCSE Co-ordinated Sciences (0654), papers are structured to test not just raw memory, but systematic scientific precision. The most common point-sink is the unit conversion failure. Students frequently substitute values directly from a question into a formula without checking the prefixes. For example, in moments calculations, using centimeters instead of meters, or in wave equations, substituting megahertz (MHz MHz) directly as hertz (Hz Hz) instantly voids the calculation marks.
