The current 2023 editions of our Core Test and Subject Module preparation books are now available as print versions and ebooks on Amazon.
In addition, older versions of our ebooks are available here on our website in English, German and Arabic.
With the TestAS book series, we want to help you prepare for this unique exam. TestAS is different from the other international tests usually encountered by high school graduates. It tests your cognitive abilities and language skills rather than your subject knowledge. To excel in the TestAS, you can prepare to master the strategies to solve the different question types. We strove exactly for this: we provide in our books the frameworks to crack the difficult and unusual question types, and to give you many questions to practice with.
Given our proximity to the students thanks to our educational consultancy, we follow the TestAS closely and adapt to the newest changes. The exercises have been created based on our research since 2014 and are updated regularly. We created practice questions whose range and depth are in line with or slightly more difficult than the actual test, so you can feel very well-prepared for the test day.
Here you can find a list of our books relevant for each subject module. Our books were designed to complement each other, and we strove to have no repeating questions.
Our goal in writing the TestAS preparation books is to give you a complete overview of and a feel for the TestAS exam. These study guides were developed after much research with a team of professionals who have themselves taken the exams. We have also interviewed dozens of TestAS test takers from diverse academic backgrounds to identify the areas where we can help the readers the most. Our guides contain test-taking skills and practice questions for the general core exam, the subject-specific modules, and the language proficiency exam onSET.
An advanced degree from a German university will pave the way for new opportunities and exciting career paths. We sincerely hope that our test preparation books will allow you to find fulfilling educational opportunities in Germany.
