★What's inside

Built to make it stick, not just to quiz you.

Answers that teach

Tap an option and the explanation appears right there — why it's correct, and why the others aren't. No flipping to page 74 of a PDF.

It remembers what you miss

Questions you get wrong quietly come back days later, right before you'd forget them. That's spaced repetition — the app does it for you.

Mock exams that feel real

Timed CAST and Generalist AD5 simulations with the actual section order, timing and pass marks. The first full run shouldn't happen on exam day.

A countdown you can trust

Set your exam date and the app keeps score: a readiness percentage, a daily goal, a streak. You always know exactly where you stand.

★The material

All questions are original, written in the style of the actual tests — and the bank keeps growing, delivered straight to the app without updates.

★Common questions

Asked before downloading.

Which exams does it cover?

The EPSO computer-based selection tests: verbal, numerical and abstract reasoning, EU knowledge and digital skills — plus full timed simulations of the CAST and Generalist AD5 formats with realistic timing and pass marks.

Is the free part actually useful?

Yes — it's a complete practice test with the same explanations and review as the paid content, not a teaser. You'll know whether the app works for you before paying.

iPhone or Android?

Both. Same app, same question bank, same one-time purchase on either store.

Is this an official EPSO app?

No. EU Nerd is an independent study aid, not affiliated with EPSO or any EU institution. All questions are original, written in the style of the real tests.

★Pricing

Pay once. Pass. Move on.

Most test-prep products bill you monthly and hope you stay subscribed. EU Nerd works the other way around: it wants you to pass and leave.
