About the AMT General test
The AMT General (Oral & Practical) knowledge test covers the foundational maintenance knowledge shared by both mechanic ratings: basic physics and electricity, materials, tools, inspections, and the regulations that govern maintenance.
You take it if you are pursuing an FAA Mechanic (A&P) certificate. The General test is required for both the Airframe and Powerplant ratings, so almost every mechanic candidate starts here.
The Mechanic, General knowledge test has 60 questions and requires 70% to pass, which is 42 correct. It is a computer-based test given at a PSI test center for a $175 fee. You must pass with 70% or higher before taking the practical test (checkride) or oral and practical for your certificate.
Aviator IQ's bank for this test holds 900 practice questions across 20 categories, each grounded in Aviation Maintenance Technician Handbook, General. Every question shows an explanation and cites the section it comes from, so a wrong answer teaches the rule rather than just marking you down.
A passing knowledge-test result is one requirement. A certificated instructor still endorses you, and the practical test or checkride is separate. Aviator IQ prepares the knowledge test so that step is behind you.
