What is the SERU pass mark?

Candidates need to demonstrate competence across all subject areas — the SERU is a competency assessment rather than a simple percentage, and you must pass each module.

How long does the real SERU take?

UK Test Hub SERU mocks use a 30-minute practice timer. Official TfL SERU timing and test-centre arrangements can change, so always check TfL’s current guidance before booking or attending the real assessment.

What do I do if I fail SERU?

You can re-sit, but TfL charges a re-test fee each attempt and may impose a waiting period. Use these mocks until you're consistently scoring well before rebooking.

Is SERU the same as Topographical?

No — Topographical tests map reading and London geography. SERU tests safety, equality and regulation knowledge. Most applicants must pass both.
