About this practice suite

This suite prepares candidates for power-plant operator selection in the energy, utilities, nuclear, mining, and natural resources sector with 5 skill areas: technical reasoning, numerical reasoning, safety judgment, situational judgment and attention and concentration. Every question was written by Novus editors for this suite — none are taken from live or leaked exams — and the full bank holds 52 scored questions across three modes, plus 8 reserve questions used to vary repeat attempts. Answer keys never ship to the browser: your answers are scored server-side, and results stay on your device.

Skills this suite practises

  • Attention and concentrationSustained focus, selective attention, and accuracy under time pressure.

Sample questions from the guided bank

Two of the 10 guided-practice questions, shown exactly as they appear in a session. Answers and explanations are not printed here — keys stay on the server — so open guided practice to answer them and see how you did.

  1. A power-plant operator's primary duty is to:

    • A. Bypass trips casually
    • B. Ignore alarms to keep output high
    • C. Monitor and control plant systems safely within approved limits
    • D. Rewrite procedures mid-shift alone
  2. A high-priority alarm clears then returns repeatedly. What is best?

    • A. Leave board unattended
    • B. Silence permanently
    • C. Assume nuisance forever
    • D. Treat as real; investigate cause and follow alarm response procedure

Practice modes and timing

Guided practice is untimed-feeling and instructional; the mini-test is a short timed check; the full simulation mirrors a complete sitting. All three draw on separate question sets, so moving up a mode never repeats what you practised.
