## What is NDT Cert Study?

NDT Cert Study is a practice-question app for anyone preparing for nondestructive testing certification exams.
It covers the main methods and code references:
• Ultrasonic (UT) Levels I and II, plus phased array (PAUT)
• Penetrant (PT) Levels I and II
• Magnetic particle (MT) Levels I and II
• Radiographic (RT) Levels I and II
• API 1104 weld acceptance-criteria questions integrated into the UT and RT tracks

Each question includes a worked explanation, so you learn why an answer is right, not just which one. The app tracks how ready you are by topic, lets you save tricky questions for another pass, and includes timed practice exams.
Everything works offline. Your progress stays on your device.
Modules unlock with a single one-time purchase. No subscription.
NDT Cert Study is an independent study aid. It is not affiliated with, endorsed by, or sponsored by API, ASNT, ISO, CGSB, BINDT/PCN, or TWI/CSWIP. All certification names and marks are the property of their respective owners.
