MIL7 practice questions - frequently asked questions

Plain answers about how MIL7 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 MIL7 exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The MIL7 exam spans 4 domains: HVAC Systems Diagnosis, Service, and Repair (15% of the exam); A/C System and Component Diagnosis, Service, and Repair (40% of the exam); Heating and Engine Cooling Systems Diagnosis, Service, and Repair (20% of the exam); Operating Systems and Related Controls Diagnosis and Repair (25% 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: A/C System and Component Diagnosis, Service, and Repair 40%; Operating Systems and Related Controls Diagnosis and Repair 25%; Heating and Engine Cooling Systems Diagnosis, Service, and Repair 20%; HVAC Systems Diagnosis, Service, and Repair 15%.

The MIL7 exam has 50 questions and is completed in 1 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
