  • Accuracy & precision: 40 questions in 6 minutes

Speed matters: nine seconds per item on average.

Accuracy and precision is the speed test used for EPSO's secretaries and clerks (AST-SC) competitions: 40 items in six minutes, about nine seconds each. Each item asks you to compare a record with its copy, a statement with a table, two lists of codes, or a totals line with its rows, and to say which element is wrong or how many match.

The discrepancies are the ones that slip through real administrative work: transposed digits, swapped day and month, O for 0, a doubled letter in a name, a total off by ten. This simulation enforces the six-minute limit and reports your time per item.

How it works

  • The timer starts when you press Start and runs until the part ends. When time is up the part is submitted automatically.
  • You can move between questions, change answers and flag questions to come back to. There is no penalty for wrong answers.
  • Keyboard: 1–5 select an option, ← → move, F flag.
  • Use a calculator-free approach: EPSO tests do not allow one, but you may use scrap paper.
