These are the high-frequency topics (based on exam breakdown + practice banks):

1. Source Inspection Basics

• Roles & responsibilities of inspector
• Authority (e.g. SIMP vs ITP vs PO)
• Ethics & communication

📌 Example:

“Which document defines inspector authority?”
✔ Answer: SIMP (Source Inspection Management Program)

2. Inspection Planning & Documentation

• Inspection & Test Plan (ITP)
• Purchase Order (PO) checks
• Vendor documentation review

📌 Repeated concept:

• What must be verified in PO?
• When to witness vs hold point?

3. Criticality & Risk-Based Inspection

• Why perform criticality assessment
• Risk vs consequence

📌 Example:

Purpose of criticality assessment?
✔ Identify equipment requiring inspection based on risk

4. Manufacturing & Fabrication

• Casting, forging, welding basics
• Heat treatment
• Material identification

👉 Questions are basic-level, not deep engineering

5. NDT (Very Common)

• RT, UT, MT, PT basics
• When to use each method
• Acceptance criteria (basic)

📌 Typical repeats:

• Which NDT detects surface cracks?
• When is UT preferred?

6. Rotating Equipment (Core Area)

• Pumps (centrifugal, reciprocating)
• Compressors
• Turbines
• Gears

📌 Frequent question styles:

• Components identification
• Failure causes
• Inspection points

7. Inspection Tools & Methods

• Measuring tools (calipers, micrometers)
• Alignment checks
• Visual inspection

8. Final Inspection & Testing

• Hydrotest vs performance test
• Documentation review before release
• Punch list handling

🔥 WHY THESE QUESTIONS ARE TRICKY

They test mindset, not knowledge:

👉 Wrong thinking:

• “Looks okay → accept”
• “Small issue → ignore”
• “I think it’s fine → decide”

• Follow process
• Escalate uncertainty
• Never assume authority
• Document everything

🧠 GOLDEN RULE (MEMORIZE THIS)

When stuck, choose the answer that:

✔ Follows procedure
✔ Involves documentation
✔ Escalates decisions
✔ Protects safety
✔ Avoids assumptions

🧠 HOW TO USE THESE DRILLS

If you got any wrong, focus on this pattern:

🔥 Weak mindset indicators:

• You chose “accept” too quickly
• You chose “reject” without escalation
• You trusted vendor too much

✅ CORRECT SIRE MINDSET (MEMORIZE)

When unsure, ALWAYS lean toward:

• 📄 Check documents
• 📢 Escalate
• 🧾 Document
• ⚠️ Protect safety
• ❌ Do NOT decide beyond authority
• 📢 Focus on inspector’s role
