A4 practice questions - frequently asked questions

Plain answers about how A4 Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real A4 exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The A4 exam spans 4 domains: Steering Systems Diagnosis and Repair (30% of the exam); Suspension Systems Diagnosis and Repair (30% of the exam); Wheel Alignment Diagnosis, Adjustment, and Repair (28% of the exam); Wheel and Tire Diagnosis and Service (12% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Steering Systems Diagnosis and Repair 30%; Suspension Systems Diagnosis and Repair 30%; Wheel Alignment Diagnosis, Adjustment, and Repair 28%; Wheel and Tire Diagnosis and Service 12%.

The A4 exam has 50 questions and is completed in 1 hour. Our timed practice mirrors that length and pacing, so exam day feels familiar.
