About the Professional Certification tests

Whether you're starting on a UK construction site, working in security, driving for TfL, or going into hospitality, you'll need a professional certification test pass. Our free CSCS, SIA, SERU TfL, Food Hygiene Level 2 and First Aid Theory mocks mirror the real exam format and give you instant explanations so you walk into your assessment ready.

What's covered

CSCS practice covers the operatives and specialist test syllabus including high-risk activities, working at height, plant and equipment, and emergency procedures. SIA mocks cover the Door Supervisor and Security Guard licence-linked exams. SERU TfL practice prepares you for the 36-question Safety, Equality and Regulatory Understanding assessment for private hire drivers. Food Hygiene Level 2 follows the standard CIEH/RSPH syllabus. First Aid mocks cover Emergency First Aid at Work theory.

Tips to pass professional certification tests

Don't underestimate them. The CSCS and SERU pass marks are high (80% and above) and rushed candidates fail more often than uninformed ones.

For SERU TfL, learn TfL terminology exactly — 'private hire' versus 'taxi', 'driver' versus 'operator'. Wording matters.

For Food Hygiene, memorise the temperature danger zone (8°C to 63°C) and the four Cs: Cleaning, Cooking, Chilling, Cross-contamination.

For First Aid, the order DRSABC (Danger, Response, Shout, Airway, Breathing, Circulation) is tested almost every time.

Why practice tests work

Professional tests are pass/fail with no second chance the same day. Practising the real format eliminates the surprise element and lets you focus on the content. Candidates who complete 3–5 full mocks before a real CSCS or SERU sitting pass at roughly twice the rate of unprepared candidates.
