The 2020 edition is the biggest Assistants edition ever and full of strategies, advice and practice exercises. The focus is on the computer-based multiple choice question tests which prove an obstacle to so many. Included are methodologies, warm-up exercises and hundreds of practice questions with answer explanations showing shortcuts and common pitfalls. Brand new features for 2020 are the specially designed warm-up exercises for tackling numerical and abstract reasoning questions, the tests which give many candidates particular difficulties. The 2020 edition also introduces an expanded guide to the whole EPSO process specifically for Assistant-level open and CAST competitions, explaining how to improve your chances and the common errors to avoid. Note: Candidates for Administrator exams should use "The Ultimate EU Test Book Administrators 2020" and those who reach the final stage Assessment Centre should use "The Ultimate EU Test Book Assessment Centre 2020"
