Our Learning Materials are free teaching materials for teachers and students developed by Linux Professional Institute. They serve as preparation for the exams and are continuously expanded and updated. With the clear structure and strict separation of explanations, exercises and solutions, they consistently follow the classroom-ready approach. The Learning Materials deal with the respective objectives of an exam in their current version. Each objective is divided into one or more lessons, depending on its scope and weight. A lesson, on the other hand, is designed for 1-2 class hours and attaches particular importance to exercises and its answers.
