Chemistry and materials roles

About this practice suite

This suite prepares candidates for chemistry and materials roles selection in the science, laboratory, agriculture, food, and environment sector with 5 skill areas: numerical reasoning, technical reasoning, safety judgment, situational judgment and data interpretation. 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

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

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. For chemistry/materials lab roles (educational), an SDS Section 2 primarily communicates:

   • A. Hazard identification (classification, signal word, pictograms, statements)
   • B. Payroll deductions
   • C. Shipping invoice totals only
   • D. Cafeteria allergen lists

2. You need 0.500 mol of NaCl (58.44 g/mol). Mass required is about:

   • A. 58.4 g
   • B. 116.9 g
   • C. 29.2 g
   • D. 5.84 g

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.
