How many questions are on the ASE A1-A8 tests?

Each ASE automobile test covers one area. On top of the scored questions, every certification test has 10 unscored research questions that you cannot tell apart, so answer everything. Recertification tests have about half the questions and no research questions.

Source: ase.com, Automobile & Light Truck Certification Tests A1-A9, checked 19 October 2026. Every question is multiple choice with one correct answer and three wrong ones. Your score is the number of correct answers and there is no penalty for a wrong answer. ASE does not publish a fixed passing percentage; the score report tells you whether you passed. Pass A1 to A8 (plus the work experience) and you are an ASE Certified Master Automobile Technician.

How much does ASE certification cost, and how do you get certified?

• Work experience: A1 to A9 need 2 years of full-time hands-on experience. A completed ASE-accredited auto program, or passing 3 or more ASE Entry-Level tests, counts for 1 year. You may take the tests first; you are certified once the experience is accepted.
• Booking: tests are taken at a proctored test center (nearly 500 in the US) or by online remote testing. After you buy a test you have 90 days to take it.
• Recertification: every 5 years. Recertification tests cost $62 each, with the total capped at $186 per order plus registration.

What you practise on MyLevel

Each practice test has 64 original questions, 8 from every A area, so one sitting shows which of the eight tests you are ready for. About a third to half are in the two-technician format: two statements, then A only, B only, Both A and B or Neither A nor B.

• A1, A2, A3: compression and leakage tests, bearing clearance, head warpage, planetary gear power flow, stall and line pressure tests, TCC shudder, clutch slip vs drag, CV and U-joints, ring and pinion setup.
• A4, A5: camber, caster, toe, thrust angle and SAI, tire wear patterns, ball joints, EPS; pedal symptoms, rotors and drums, fluid types, bleeding, ABS sensors.
• A6: Ohm's law calculations, series and parallel circuits, voltage drop, parasitic draw, battery tests, relays and CAN bus resistance.
• A7, A8: A/C pressure diagnosis, R-134a and R-1234yf, Section 609; fuel trims, O2, MAP and ECT sensors, misfires, catalyst efficiency, EVAP and EGR.

ASE also sells its own Official ASE Practice Tests at $14.95 each (20 to 25 questions per area, about half a real test, ase.com/testing). MyLevel is a different, independent product: 2 full mixed tests for $9.99, a one-time payment with no subscription, which also unlocks every other MyLevel job test.

How to pass the ASE tests

• Handle Technician A / B questions statement by statement: decide whether A is true on its own, then B on its own, and only then pick the answer. Do not let one true statement make you accept the other.
• Think like a diagnostician: most questions describe a symptom and ask for the most likely cause or the next test. Ask what the cheapest, most direct check would be.
• Learn the classic links: spongy pedal = air, sinking pedal = master cylinder bypass, pull toward more camber and less caster, positive fuel trim = lean, both A/C pressures high = overcharge or poor condenser airflow.
• Practise the maths: Ohm's law and power (W = V × A) come up on A6 and elsewhere.
• Start with your strongest areas: take a full mixed test, look at your score per area, and book the ASE tests you score highest on first. Retake your weakest area after studying the explanations.
