API 653 practice questions — free 10-question sample

Ten questions drawn from Test 1 of the API 653 Aboveground Storage Tank Inspector bundle, spread across the exam's domains rather than taken from the top. Every answer carries the same explanation a paying customer sees. No sign-up, no email, nothing to install.

What is in the full API 653 bundle?

The complete set is 6 practice tests and 1,020 questions — the sample above is ten of them. Each test runs to the real exam's length and timing, and every question has a written explanation covering why the right answer is right and why each distractor is wrong.

Which topics do these questions cover?

The bank follows the published blueprint. The ten free questions sample across these areas:

• I. Calculations & Tabular Evaluations for Evaluating Thickness Measurements, Weld Sizes, and Tank Integrity
• II. Welding on Atmospheric Aboveground Storage Tanks
• III. Nondestructive Examination
• IV. Practical Knowledge - General
• V. Practical Knowledge - Specific

How should you use a free sample?

Answer all ten before reading any explanation, then read every explanation including the ones you got right — a guess that lands is not knowledge, and the explanation is where you find out which it was. If you score well, the value of the full set is the volume and the timing; if you do not, it tells you which domain to open first.

Independent and unofficial. All questions are original and no exam content is reproduced.
