Reliability and maintenance engineering

About this practice suite

This suite prepares candidates for reliability and maintenance engineering selection in the engineering, technical, and design sector with 5 skill areas: technical reasoning, numerical reasoning, data interpretation, situational judgment and safety judgment. 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

• Technical reasoning — Applied technical principles, diagrams, tools, systems, measurements, and troubleshooting.
• Numerical reasoning — Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.
• Data interpretation — Tables, charts, graphs, dashboards, trends, comparisons, and evidence-based conclusions.
• Situational judgment — Evaluating workplace responses against role-relevant principles.
• Safety judgment — Hazard recognition, safe sequencing, escalation, and risk controls.

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. MTBF primarily measures:

   • A. Average operating time between failures for repairable items
   • B. Mean time to paint equipment
   • C. Maintenance crew overtime only
   • D. Spare-parts warehouse volume

2. A critical pump fails twice in one week after a rushed seal change. What is best?

   • A. Stop-and-fix with root-cause analysis before returning to run-to-fail
   • B. Replace seals again without investigating
   • C. Blame the night shift and move on
   • D. Disable vibration alarms to reduce noise

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.
