API 510 Prep
613 original questions across all 11 Body of Knowledge domains, timed mocks that mirror the real two-section paper, and a predicted score that tells you when you are ready to book.
Everything on the API 510 Pressure Vessel Inspector certification: what is on the exam, what it costs, and free questions you can sit now.
The right API 510 resource depends on whether you are short of questions, teaching or the codes themselves. Here are ten options, ordered by how well each serves that question.
Exam guideThe Body of Knowledge tells you what is examinable. It does not tell you how much each area is worth, which is the question everyone actually wants answered.
CostThe exam fee is the small part. Most candidates are surprised by the standards, and by the bill that lands again three years later.
ResourceHere is a free PDF, no sign-up. It is the sheet you would write out the night before. Then, further down, the straight answer about the code itself.
Exam guideThe exam is not offered continuously. It runs in windows, the application closes long before the window opens, and picking the wrong one changes which editions you are studying.
PracticeMost people fail the calculations and the judgement questions, not the recall. Here is what the real ones look like, and ten you can sit right now.
CareersThe honest answer is that the certificate does not set your salary. It changes which jobs will look at you at all, and that is where the money actually comes from.
