The most direct links:

Electricity and electromagnetism (91173): shares this standard's Excellence-level "linked chain of reasoning" habit Both externals reward several true statements explicitly LINKED into one chain of reasoning, rather than a disconnected list — practising one sharpens the other. Mechanics (91171): the same "draw the diagram first" discipline applies to ray diagrams here and force/motion diagrams there Both standards are graded heavily on a correctly constructed diagram — the position, size and orientation of everything else in the answer follows directly from getting the diagram right first. ✓

The big picture in one sentence

Every part of this paper rewards the SAME habit: draw the diagram (ray, wave, or pulse) accurately FIRST, then read the answer's numbers and properties off that diagram rather than guessing at them.
