Everything you need to pass, in one course
Most exam prep stops at a list of questions. Our courses teach the topic first, help you remember it, then test you under exam conditions.
Interactive study modules
Chapter-by-chapter lessons that follow the ASNT body of knowledge, written for working inspectors and engineers.
Animated explanations
Sound beams, magnetic fields, radiation geometry and eddy current fields shown in motion, so difficult principles make sense quickly.
Flashcards
Key terms, formulas and code requirements in quick-review cards, ideal for short sessions on your phone.
Chapter quizzes
Check each topic as you finish it, so weak areas show up early rather than in the exam.
Explained question bank
Thousands of exam-style questions, each with a detailed explanation of why the answer is right and the others are wrong.
Timed mock exams
Full-length, computer-based mock exams that match the real format and timing, with a score and review at the end.
A proven routine from first lesson to exam day
Every course follows the same four stages, so you always know what to do next.

Under ASNT SNT-TC-1A, who is responsible for certifying NDT personnel?
- A. ASNT
- B. The employer
- C. The training provider
- D. The customer
Show answer and explanation
B. The employer. SNT-TC-1A is a recommended practice. Each employer writes its own written practice and certifies its personnel against it. ASNT certifies individuals only through its own central programmes, such as ASNT NDT Level III.
Raising the tube voltage (kV) while keeping all other factors the same mainly…
- A. Increases subject contrast
- B. Increases penetration and lowers subject contrast
- C. Reduces geometric unsharpness
- D. Has no effect on the image
Show answer and explanation
B. Higher kV produces more penetrating radiation. Thick and thin sections then absorb more similarly, so subject contrast falls. Geometric unsharpness depends on focal spot size and geometry, not kV.
