How many questions are on the SERU test?
The live TfL SERU assessment has 37 questions in total. They are a mix of multiple-choice questions and sentence completion (fill-in-the-blank) questions, all based on the TfL PHV Driver’s Handbook.
Question types
- Multiple-choice (around 20 questions): You choose one correct answer from several options. Some questions may be grouped with a short reading passage (reading-style MC).
- Sentence completion (around 17 questions): A sentence has a missing word or phrase. You choose the option that correctly completes the sentence. These test the same handbook content in a different way.
Practising both types helps you get used to the real exam and improves your timing and accuracy.
What topics are covered?
All 37 questions draw from the 10 sections of the TfL PHV Driver’s Handbook: London PHV Driver Licensing, Licensing Requirements for PHVs, Carrying out Private Hire Journeys, Staying Safe, Driver Behaviour, Driving and Parking in London, Safer Driving, Equality and Disability, Safeguarding Children and Adults at Risk, and Ridesharing. The exact mix of topics in your test is set by TfL.
Pass mark and timing
TfL sets the official pass mark for the SERU assessment. In preparation, many drivers aim for at least 70% to give themselves a buffer. You typically have a set time to complete the test; practising under timed conditions will help you manage your pace on the day.
Why practise in the 37 format?
Sitting a practice exam that matches the real SERU 37 format—same number of questions and the same mix of multiple-choice and sentence completion—reduces surprises and builds confidence. PassSERU’s SERU 37 practice exam mirrors this structure so you can prepare effectively.
