A1 practice questions - frequently asked questions

Plain answers about how A1 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 A1 exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The A1 exam spans 5 domains: General Engine Diagnosis (40% of the exam); Cylinder Head and Valve Train Diagnosis and Repair (13% of the exam); Engine Block Diagnosis and Repair (9% of the exam); Lubrication and Cooling Systems Diagnosis and Repair (18% of the exam); Fuel, Electrical, Ignition, Air Induction and Exhaust Systems Diagnosis and Service (20% 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: General Engine Diagnosis 40%; Fuel, Electrical, Ignition, Air Induction and Exhaust Systems Diagnosis and Service 20%; Lubrication and Cooling Systems Diagnosis and Repair 18%; Cylinder Head and Valve Train Diagnosis and Repair 13%; Engine Block Diagnosis and Repair 9%.

The A1 exam has 55 questions and is completed in 1 hour 15 minutes. Our timed practice mirrors that length and pacing, so exam day feels familiar.
