Why Students Lose Marks in IGCSE Physics Paper 4 0625:0972 – Structured Questions

Most students do not lose marks in IGCSE Physics Paper 4 because they don’t know Physics —
they lose marks because they don’t answer the way examiners expect.
In this video, Nancy breaks down the real reasons students lose easy marks in
IGCSE Physics Paper 4 (0625 / 0972), especially in structured questions.
You will learn:
Why command words (state, explain, describe, calculate) are often misunderstood
How missing units can cost you final marks even with correct calculations
Why no working = no method marks
The danger of rounding too early and incorrect significant figures
Common data copying and unit conversion mistakes
How choosing the wrong formula loses marks despite memorisation
Why vague explanations score zero without Physics keywords
How poor diagrams cost guaranteed marks
Why answers must match the number of marks
How mark schemes and examiner reports reveal exactly what earns marks
This lesson shows you how to:
Think like an examiner
Structure answers for maximum marks
Turn average answers into A / A* responses
📘 Who this video is for
IGCSE Physics students (0625 / 0972)
GCSE Physics students
AS & A Level students improving exam technique
Students aiming for top grades
