Prepare for SERU, Topographical Skills and Speaking & Listening in one app for London private hire vehicle (PHV) drivers. Try a free mock test, practise with 1,000+ SERU questions and use interactive theory, study guides and audio practice papers to get ready for your assessments. Whether you’re applying for your first London PHV driver licence or completing an assessment as an existing driver, you can move from studying the theory to practising questions, taking timed mocks and reviewing your results. Focus on the assessment you have coming up or switch between sections as you revise. SERU STUDY AND PRACTICE Prepare for the Safety, Equality and Regulatory Understanding (SERU) assessment with structured materials based on publicly available TfL guidance. Study all 10 SERU chapters plus the Guide chapter and revise topics such as licensing rules, passenger safety, safeguarding and equality. • Work through interactive theory and use the study guides and support materials to revisit topics. • Practise with 1,000+ SERU questions to check what you’ve understood. • Use multiple-choice questions to test your knowledge and fill-in-the-blank questions to practise completing sentences. • Read short passages and answer paragraph-based multiple-choice questions. FREE MOCK TEST AND TIMED PRACTICE Start with a free mock test to get familiar with the question styles. When you’re ready to practise under time pressure, take a timed, assessment-style mock test. Review your answers afterwards and look back at previous attempts to see which topics or question formats need more attention. TOPOGRAPHICAL SKILLS Build the map-reading and navigation skills you’ll need for the Topographical Skills assessment. Study all 5 theory chapters and refer to the Topographical Skills Guide and reference materials as you practise. • Index study. Use the index to look up streets and find them on an A–Z map. • Compass points. Identify compass points and practise working out directions on a map. • General topography. Review the theory alongside the map-reading and navigation exercises. • Map reading and road finding. Practise locating roads and using the map to work out where places are in relation to one another. • Navigation and directions. Use A–Z map exercises and compass-direction practice to build confidence interpreting directions. For separate route-planning practice and training, contact The London Training Zone at https://theltz.com/ SPEAKING & LISTENING Build familiarity with the types of tasks you may encounter in the Speaking & Listening assessment. Use the study materials and multiple audio-based practice papers to work through the questions at your own pace. • Read and study the questions alongside the practice audio. • Replay recordings whenever you need to hear them again or check a detail. • View the answers as you study and use them to review your responses. • Continue practising with a growing collection of Speaking & Listening materials. TRACK YOUR PROGRESS Create your profile to monitor your study progress and test results. Look back at past tests, review your answers and see how your scores change over time.
