"Free EPSO resources" usually means one of two things: genuinely useful material that happens to cost nothing, or thin samples designed to funnel you somewhere. This list is strictly the first kind. Twelve resources — our own free tier included, official EPSO material, and the study sources the questions are actually written from — with an honest note on what each one is best for, because the real skill of free preparation is matching the resource to the phase you are in.
If you want the full strategic picture first — tracks, scoring weights, the 12-week plan — that lives in the EPSO Preparation 2026 complete guide. This page is the toolbox.
Free practice: build volume and pacing
1. Free weekly EPSO tests — all five test types
Our practice hubs run a free timed set for every computer-based test type — verbal, numerical, abstract reasoning, EU Knowledge and digital skills — rotating to a fresh set every Monday. Questions are served easiest-first at real exam difficulty, and each hub carries the full format guide (questions, timing, pass marks per the Notices in force) so you learn the rules while you practise. Best for: your first diagnosis, and a weekly pulse-check per test type.
2. Question of the Day
Six fresh questions daily — one per test type plus a rotating specialist field — with complete per-option explanations. Fifteen minutes with your morning coffee, and in a month you have touched 180 questions across every format without scheduling a single study session. Best for: maintenance between focused blocks, and keeping every format warm.
3. The free mock PDF
A full printable EPSO-style mock — delivered free by email from any blog article — for candidates who think better on paper, or want a simulation they can sit away from a screen. Best for: one clean offline dress rehearsal.
4. Free preparation tools
Twelve small tools: study planners, score calculators, deadline trackers, eligibility checkers. None of them teaches you verbal reasoning; all of them remove the administrative friction that quietly eats study hours. Best for: the planning layer around your actual practice.
Official material: the resources most candidates skip
5. EPSO's official sample tests
EPSO publishes sample questions per test type, including the mock-test PDF for the current competition model. The volume is small — these are examples, not a question bank — but they are the ground truth for format, wording style and difficulty philosophy. If a third-party resource contradicts the samples, trust the samples. Best for: calibrating your expectations against the source.
6. The Notice of Competition — the exam blueprint
Free, public, in the Official Journal, and unread by a startling share of candidates. Your Notice defines the tests, the timing, the pass marks, the language rules and — for specialists, in Annex II — the exact syllabus of the field test. Reading it twice is the highest-return hour in all of EPSO preparation; the eligibility guide covers the criteria side. Best for: knowing precisely what you are preparing for, from the primary source.
7. EUR-Lex and europa.eu — study where the questions come from
The EU Knowledge test is written from official sources: EUR-Lex for treaties and legislation, europa.eu factsheets for institutions and policies. Studying from the same material the question-writers use is not a trick — it is the syllabus. Pair reading with practice questions to find which of the topic areas actually cost you points. Best for: systematic EU Knowledge study that transfers directly.
8. The ABC of EU law
A free Publications Office book that explains the legal order — treaties, institutions, legal acts, case-law principles — in readable prose. The single best free grounding for the legal spine of EU Knowledge. Best for: building the foundation before drilling MCQs.
Guides, plans and community
9. The complete preparation guide
Track choice, every test format verified against the Notices, the scoring arithmetic that should allocate your hours, and the 12-week plan — all in one long read, free like the rest of the blog's fifty-plus guides. Best for: strategy before tactics.
10. Specialist and CAST deep-dives
If your route is not AD5, the map differs: the specialist competitions guide covers every open AD7/AST field and the FRMCQ that ranks you; the CAST guide covers the always-open contract-agent door, its three tests and its 10-year validity rule. Best for: candidates whose competition is not the famous one.
11. The EPSO 2026 calendar
What is open, what is announced, what closes soon — because the cheapest preparation mistake is discovering a deadline after it passed. Best for: timing your campaign.
12. The candidate community
The unofficial candidate forums and groups — r/EUCareers on Reddit chief among them — are where you find lived experience: how invitations actually arrive, how the remote proctoring feels, what recruiting services asked in interviews. Treat factual claims with care (the Notice always wins), but as texture and morale, the community is genuinely valuable and genuinely free. Best for: the questions no official page answers.
What free resources will not do — and when that matters
An honest close. Free preparation covers diagnosis, format familiarity, official study material and daily maintenance — a complete toolkit for the early and middle phases. What it thins out at is the final phase: large pools of questions calibrated to real difficulty, per-option explanations that teach why every wrong answer is wrong, analytics that find your weak patterns, and full timed simulations under exam conditions. That feedback loop is what the paid tier adds, with 44,000+ verified questions across five languages — and a free account to start, so the upgrade decision can wait until your diagnostic scores tell you whether you need it.
Either way, start with the free dozen above. The candidates who fail EPSO rarely fail for lack of paid tools; they fail for lack of structured practice — and structure, as this list shows, costs nothing.
