The revised Ultimate EU Test Book - Assistant (AST) Edition 2015 focuses particularly on the so-called pre-selection tests in EPSO exams as this is where the great majority of candidates fail - in many cases because of lack of proper preparation. The book includes chapters on the skills and techniques involved in tackling verbal, numerical and abstract reasoning questions, with comprehensive practice exercises designed to simulate AST-level competitions. Multiple choice questions are accompanied by detailed answer explanations to enable you to understand your mistakes and improve your speed and accuracy. The book also includes situational judgement tests, with practice scenarios as well as the tests in prioritising and organising, and in accuracy, faced by AST candidates. Other chapters describe the EPSO exam process from start to finish and explain the competencies tested and exercises faced by those who win through to the Assessment Centre.
