ASE A4 Cheat Sheet.
The night-before summary, built like the exam.

The numbers to remember

• 60 minutes total time limit for the whole test.
• 50 total questions, but only 40 are scored toward your result.
• 10 unscored research questions are mixed in for future test development — you can't identify which ones they are, so answer every question fully and with equal care.
• $62 general test fee, plus a separate $34 registration fee per order (the registration fee is per order, not per individual test).
• Certification is valid for 5 years before recertification testing is required to keep it current.

Blueprint areas and weights

• Steering Systems Diagnosis and Repair — 12 questions (columns, pumps, racks, gears, linkage).
• Suspension Systems Diagnosis and Repair — 12 questions (springs, struts, shocks, control arms, ball joints, bushings).
• Wheel Alignment Diagnosis, Adjustment, and Repair — 11 questions (camber, caster, toe, and alignment-related diagnosis).
• Wheel and Tire Diagnosis and Service — 5 questions (wear patterns, wheel balance, tire/wheel assembly service).
• Steering and suspension together make up over half the scored test (24 of 40 questions) — study those two areas first if your time is short.

Diagnostic quick rules

• Verify the complaint and the conditions under which it occurs before diagnosing anything.
• Inspect visually first — many suspension and steering faults (worn bushings, leaking struts, uneven tire wear) are visible before any tool is used.
• Isolate the system: steering, suspension, and alignment symptoms frequently mimic one another on a road test, so rule systems in or out methodically.
• Confirm the fix afterward — re-check alignment angles and steering feel, don't assume a repair is complete just because a part was replaced.

Top traps

• Technician A/B questions: read both statements fully before judging either one; 'both correct' and 'both incorrect' are legitimate answers, not just fallback choices for when you're unsure.
• Absolute words like 'always' or 'never' in a technician statement are frequently the signal of the wrong choice.
• Certification requires the test and documented work experience (formal vocational training can count toward it) — passing the test alone does not equal being certified.
• Don't confuse the 5-year certification validity period with the test's 60-minute time limit — they're separate numbers candidates often mix up under pressure.
• Study time spent evenly across all four content areas wastes effort; weight your review to match the 12/12/11/5 question split instead.
