ExploreAbout this exam
This page supports candidates preparing for an EPSO AST/SC competition - the selection process used by the European Union to recruit assistants, secretaries and clerks for its institutions and bodies. It is written for people who want a structured, independent way to practise the reasoning and behavioural skills such competitions typically assess, and who need a realistic sense of what preparation actually demands. The practice material is organised around four domains: verbal reasoning, numerical reasoning, abstract reasoning, and situational judgement or organisational skills. Each domain is treated as a separate skill with its own question style, timing pressure and failure patterns, so you can diagnose weak areas rather than revise everything at once. Preparation advice on this page focuses on method: working under time limits, reviewing every wrong answer for the reasoning error behind it, and building a repeatable weekly routine rather than cramming. Important caveat: the official EU Careers pages consulted for this page returned 'Page not found', so no exam-specific figures - question counts, duration, pass marks, fees or domain weightings - could be verified. Treat all such numbers as unknown until you read the current notice of competition in the 'Competitions and selection' section of the official EU Careers site. This platform is independent and is not affiliated with EPSO or any EU institution.
What you'll study
About EPSO AST/SC preparation
How do I find the official format and dates for an AST/SC competition?
Go to the official EU Careers site, which the source confirms is managed by the Directorate-General for Human Resources and Security, and open the 'Competitions and selection' section. The notice of competition published there is the only authoritative source for eligibility, test format, dates and pass marks. This page could not verify those figures because the source pages returned 'Page not found'.
What does the AST/SC exam actually test?
Practice material for this competition is organised around verbal reasoning, numerical reasoning, abstract reasoning, and situational judgement or organisational skills. Expect to read dense passages and judge whether statements follow, to work quickly with percentages, ratios and tables, to spot patterns in sequences and shapes, and to choose the most professional response to workplace scenarios. Confirm the official scope in the current notice.
How difficult is it, and is speed really a problem?
Difficulty comes less from individual questions than from volume under a clock. Most candidates can solve items untimed; the challenge is sustained accuracy across many items with little recovery time. Train with strict timing from early on, then analyse errors afterwards without a clock. If you only ever practise untimed, you will misjudge your real pace on the day.
Can I retake the competition if I fail?
The source does not state a retake policy, so this cannot be confirmed here. Retake and re-application rules depend on the specific competition and are set out in its notice. Read the notice and any EPSO guidance on reapplying before assuming you must wait a fixed period. Never rely on secondhand claims about retakes.
How much time should I plan for preparation?
No official figure exists, so plan from your own diagnostic. Take one timed set per domain, record accuracy and completion rate, then allocate most hours to the weakest domain while keeping short weekly sessions in the others so skills do not decay. Consistency across several weeks beats a few long sessions, especially for abstract reasoning, which improves through frequent short drills.
In what order should I study the four domains?
Start with a diagnostic across all four, then prioritise the domain where your timed accuracy is lowest, because score gains are usually largest there. Keep numerical and abstract reasoning in short, frequent sessions since they reward repetition. Verbal reasoning benefits from error analysis of why an option looked attractive. Situational judgement needs discussion or written justification, not just answer-checking.
What are the most common reasons candidates underperform?
Three recur. First, misreading the question stem and answering a related but different question. Second, over-investing in one hard item and losing time for easier ones later. Third, reviewing only whether an answer was right, not why the chosen option was tempting. Fix these by marking questions you will return to, forcing a move-on rule, and writing one line of reasoning for every mistake.
Does this page or platform have any official status?
No. This is independent study material and is not affiliated with EPSO, the European Commission or any EU institution. It is designed to complement, not replace, the official notice of competition and any sample tests published by EU Careers. Always check the official EU Careers 'Competitions and selection' section for binding rules, dates and formats before making decisions about your application.
How should I use practice tests without wasting them?
Use a small number for diagnosis, then reserve full timed sets for later stages. After each set, log every error by cause: knowledge gap, misread stem, timing pressure or careless slip. Rework those items a few days later without notes. Repeating the same test immediately inflates your score through recognition and hides the weaknesses that will cost you marks in the real sitting.
