How often each topic actually gets tested

Confirmed tested — cars/trailers, pulleys, pegs, lifts — in 7 of the 17 series this course has reviewed a genuine primary source for, the highest count found for any WME01 topic. When it takes the pulley-then-free-motion shape, it's also the paper's final, heaviest question in both of the two fully mark-mapped recent series (15 marks Jan 2025, 17 marks Jun 2025).

Confirmed in 6 of the 17 series reviewed, most often built around an 'about to tilt' condition rewarding an efficient pivot choice. Sits in the paper's middle third in 5 of those 6 instances — never the opener, never the final question, a real contrast with connected particles/pulleys, which does anchor the final question.

Confirmed in 5 of the 17 series reviewed, set on an incline in 3 of those 5 (one confirmed exception: a rough horizontal plane, Jun 2024). Where it's a dedicated question it lands at an 11–12 mark tariff in all three series with a recovered total, always mid-to-late paper and never the final question.

The topic itself is confirmed present in 5 of the 17 series reviewed. Its single sharpest trap — reporting a signed velocity where the question asked for an unsigned speed — is independently confirmed in 3 of those (Jan 2020, Oct 2022, Jun 2024), every one at Q1. Consistently an early question, never a late high-mark one.

Seen in 5 of 17 series reviewed, but only 3 of those are the topic's own core question — a bearing, resultant, or position vector genuinely being the subject; the other 2 cite Lami's theorem only, as a credited alternative method inside an equilibrium question. The two most recently mapped series (Jan 2025, Jun 2025) both blend this topic into Newton's second law or kinematics rather than testing it bare.

The core trap — one suvat equation silently run across two genuinely different acceleration phases — is confirmed in only 2 of the 17 series reviewed (Jan 2023, Jun 2024); widened to include the connected-particles-then-free-motion hybrid sharing the same handover discipline, 4 of 17. Every time this topic (plain or hybrid) has a recorded mark total, it has been a substantial 14–17 mark allocation, never a short item — three data points, not yet a rule.

The bare, friction-free form this lesson actually teaches is confirmed in only 2 of the 17 series reviewed (Jan 2022, Jan 2023); widened to include series where it appears blended into a friction/incline question instead, 4 of 17. Neither of the two most recently mapped series (Jan 2025, Jun 2025) shows the bare form at all — both blend it with friction.

Confirmed to anchor part of a question in only 3 of the 17 series reviewed — but in both of the two series this course has fully mark-mapped question-by-question (Jan 2025, Jun 2025), it appeared. Never seen tested standalone: every confirmed instance pairs it with a second spec point (a resultant's direction, or a resolution step) inside the same question.

The thinnest topic in the unit, by this course's own research: confirmed in only 2 of the 17 series reviewed, and the one spec topic that failed to anchor any question at all in both of the two fully mark-mapped recent series (0 of 2, against every other topic's 2 of 2). Never a standalone question — always the final 2–3 marks riding on a question already tariffed for something else. ('Show that' as a command word is far more common, roughly 5 of 17, but that's a cross-topic instruction, not evidence for this spec point specifically.)
