About this practice suite
This suite prepares candidates for data analyst selection in the technology, software, data, ai, and cybersecurity sector with 5 skill areas: data interpretation, numerical reasoning, critical thinking, logical reasoning and situational 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
- Data interpretation: Tables, charts, graphs, dashboards, trends, comparisons, and evidence-based conclusions.
- Numerical reasoning: Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.
- Critical thinking: Evaluating evidence, assumptions, arguments, credibility, and alternative explanations.
- Logical reasoning: Conditional logic, syllogisms, ordering, grouping, argument structure, and constraint problems.
- Situational judgment: Evaluating workplace responses against role-relevant principles.
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, because keys stay on the server. Open guided practice to answer them and see how you did.
Orders (order_id, customer_id) joined INNER to Customers on customer_id. Rows with unknown customers:

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.
| Mode | Questions | Duration | Start |
|---|---|---|---|
| Guided practice | 10 | 15 minutes | Open |
| Timed mini-test | 12 | 18 minutes | Open |
| Full simulation | 30 | 45 minutes | Open |
