The workbook offers a collection of practice exercises from various key subject areas as outlined in the curriculum, including foundational topics. Depending on their level of knowledge, students can either use the sample problems to assist themselves with complex tasks, work on the exercises independently, and verify the correctness of their reasoning using the fully worked-out solutions. This approach helps them more easily manage uncertainties in a chapter and allows them to prepare specifically for questions in schoolwork, oral exams, or retake exams.
