Angles, area, perimeter, circles, transformations, and 3D measure questions.
Diagram questions can be very mark-efficient when the student knows which facts to pull out first.
Paper focus: Diagram-heavy method marks. Tiers: Foundation and Higher.
Train the habit of annotating the diagram before calculating anything.
Start with Angle facts, then use the app tools to practise, upload an answer, or ask for an explanation.
