Most candidates can describe Speed hump. The Thai exam tests whether you can pick it out of a roadside scene under time pressure and choose the right response. Practising it inside the question flow is what closes that gap.
Now see it in questions.
Spotting Speed hump in isolation is one thing. Recognising it inside a real exam-style question, among lookalikes and trick wording, is another. The diagnostic mixes it in for you.
