About this mock

Difficulty: Intermediate

Topographical Mock 20 tests bridge and tunnel choices through private hire service examples with practical clues. The questions use bridge and tunnel choices to connect major crossing recognition, river-side comparison and route-distraction spotting with clear answer evidence. A lower score points to crossing-purpose checks before another mixed mock. On Topographical Mock 20, feedback should lead back to bridge and tunnel choices.

Common mistakes in this mock

Using a crossing that sends the route away from the destination
