Where marks are lost
Common Cambridge IGCSE Maths mistakes
Rounding part-way through.
Keep full calculator values until the last line. Cambridge wants non-exact answers to 3 significant figures, and angles to 1 decimal place, unless the question says otherwise.
Measuring the diagram.
Diagrams marked “NOT TO SCALE” can’t be measured. Work out lengths and angles from the facts you’re given.
Giving geometry reasons in your own words.
Use the standard reasons, such as “angles in the same segment are equal” or “alternate angles”. Vague reasons often lose the mark.
