About this app

Preparing for an EU competition shouldn't cost a small fortune. EU Nerd is a dedicated practice tool for EPSO selection tests, built by candidates who successfully passed the EPSO selection process.

We grew tired of preparation materials that didn't match the format of the actual tests and platforms that charged expensive monthly subscriptions. We built the tool we wished we had: realistic questions, instant explanations. Questions reviewed by a human, ensuring you get practice that reflects the actual exam. How do we know? Because we already passed them.

Why EU Nerd
• Five test types in one app: Complete coverage for Verbal Reasoning, Numerical Reasoning, Abstract Reasoning, EU Knowledge, and Digital Skills.

• 1,400+ original questions: A growing bank of practice material designed to mirror the difficulty and format of EPSO tests. We will add more questions later. The questions will be periodically updated.

• NO AI Slop: Don´t expect lame AI-generated ballast. Questions have been built by humans who have passed the official tests.

• Realistic mock exams: Full, timed simulations for CAST and Generalist AD5 procedures.

• Spaced repetition: The app remembers which questions you get wrong and reintroduces them to reinforce your weak spots.

• Instant explanations: Detailed solutions are explained after each question to enable you to learn the patterns the cognitive-based tests (CBT) use.

• Exam countdown: You can set your exam date to track your daily practice streak and readiness score.

• Test vs Practice mode: In practice mode, you see the right answer and a clear explanation straight after each question. Switching to test mode enables you to simulate the real test under timed conditions.

• Offline: practice on your daily commute, on the beach, or while on the plane. You do not need an internet connection.

MEET COACH
We added a personalized feature: the coach is your personal study plan. It reads your own answers, finds exactly where you are losing marks, and turns your weak spots into targeted practice. It tells you whether you would pass against the real EPSO pass marks, lays out what to do each day up to your exam, and keeps you on pace. Coach is an optional upgrade.

Disclaimer: EU Nerd is an independent study aid. It is not affiliated with, endorsed by, or connected to the European Personnel Selection Office (EPSO) or any European Union institution. All questions are original content and do not reproduce official exam material.
Prepare for your EU career.
