S6 practice questions - frequently asked questions

Plain answers about how S6 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 S6 exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The S6 exam spans 7 domains: General Electrical/Electronic System Diagnosis (13% of the exam); Low-Voltage Battery Diagnosis and Service (9% of the exam); Starting System Diagnosis and Repair (13% of the exam); Low-Voltage Charging System Diagnosis and Repair (16% of the exam); Lighting Systems Diagnosis and Repair (27% of the exam); Gauges and Instrument Warning Devices Diagnosis and Repair (9% of the exam); Miscellaneous (13% 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: Lighting Systems Diagnosis and Repair 27%; Low-Voltage Charging System Diagnosis and Repair 16%; General Electrical/Electronic System Diagnosis 13%; Starting System Diagnosis and Repair 13%; Miscellaneous 13%; Low-Voltage Battery Diagnosis and Service 9%; Gauges and Instrument Warning Devices Diagnosis and Repair 9%.
