🚫 No:

  • Code searching in first pass
  • long calculations
  • re-checking answers

 

 

Yes:

  • pattern recognition
  • elimination

🧮 ROUND 1 — CALCULATION SPEED (Q1–Q10)

Q1

0.600 → 0.450 in 5 years → CR?

👉 Pattern: loss ÷ time
✔ Answer: 0.030 in/yr

 

 

 

Q2

t=0.300, tmin=0.200, CR=0.025 → RL?

👉 Pattern: (t – tmin)/CR
✔ Answer: 4 years

 

 

 

Q3

RL = 6 → interval?

👉 Pattern: RL ÷ 2
✔ Answer: 3 years

 

 

 

Q4

Height 20 ft → pressure?

👉 Pattern: 0.433 × h
✔ Answer: 8.66 psi

 

 

 

Q5

0.800 → 0.600 in 10 yrs → CR?

✔ Answer: 0.020

 

 

 

Q6

t=0.400, tmin=0.250, CR=0.050 → RL?

✔ Answer: 3 years

 

 

 

Q7

RL = 8 → interval?

✔ Answer: 4 years

 

 

 

Q8

Height 30 ft → pressure?

✔ Answer: 12.99 psi

 

 

 

Q9

0.500 → 0.410 in 3 yrs → CR?

✔ Answer: 0.030

 

 

 

Q10

t=0.280, tmin=0.180, CR=0.020 → RL?

✔ Answer: 5 years

 

 

 

📏 ROUND 2 — FAST DECISION (Q11–Q20)

Q11

t < tmin → action?

✔ Immediate repair / derate

 

 

 

Q12

RL ≤ 0 → meaning?

✔ Immediate action required

 

 

 

Q13

Bottom corrosion risk?

✔ Highest risk zone

 

 

 

Q14

External inspection sees bottom corrosion?

✔ NO

 

 

 

Q15

RBI purpose?

✔ Adjust frequency only

 

 

 

Q16

Repair means?

✔ Restore condition

 

 

 

Q17

Alteration means?

✔ Design change

 

 

 

Q18

Uniform settlement?

✔ Usually acceptable

 

 

 

Q19

Edge settlement?

✔ High risk

 

 

 

Q20

Internal inspection?

✔ Bottom condition check

 

 

 

🔍 ROUND 3 — RAPID IDENTIFICATION (Q21–Q30)

Q21

MIC stands for?

✔ Microbiologically influenced corrosion

 

 

 

Q22

CUI occurs where?

✔ Under insulation

 

 

 

Q23

Pitting vs uniform?

✔ Localized = more dangerous

 

 

 

Q24

On-stream inspection?

✔ Tank operating

 

 

 

Q25

Inspection interval formula?

✔ RL ÷ 2

 

 

 

Q26

Corrosion rate increases → RL?

✔ Decreases

 

 

 

Q27

Thickness decreases → risk?

✔ Increases

 

 

 

Q28

Height increases → stress?

✔ Increases

 

 

 

Q29

Shell vs bottom failure?

✔ Bottom first

 

 

 

Q30

Code search strategy?

✔ Keyword scanning only

 

 

 

⚡ SCORING RULE (SELF-CHECK)

🟢 Strong speed (PASS-ready)

  • 25–30 correct in <30 sec thinking
  • minimal hesitation

 

 

🟡 Medium speed

  • 18–24 correct
  • some hesitation

 

 

🔴 Weak speed

  • <18 correct
  • overthinking or slow recall

 

 

🧠 WHAT THIS TRAINING FIXES

It fixes:

  • RL/CR hesitation

  • calculation delay

  • inspection confusion

  • code panic

  • overthinking

❌ It removes:

  • slow reading

  • deep analysis habit

  • hesitation loop

 

 

 

🚀 DAILY USE PLAN (VERY IMPORTANT)

🔁 Do this for 3 days:

  • 3 rounds/day
  • 30 questions each round
  • strict 30-second timer

 

 

🎯 Goal after 3 days:

Instant recognition without thinking

 

 

 

🧠 FINAL EXAM MINDSET

“I don’t solve slowly. I recognize and move.”
