While preparing for my Abitur, I was frustrated by the lack of resources for learning and practicing all the functions of the graphical calculator. To solve this problem, I wrote a 50-page book with sample problems and step-by-step guides on how to use the calculator effectively for specific exam tasks.
The book is available for purchase on Amazon and can also be downloaded as a free PDF. To date, it has been downloaded more than 5,000 times, helping thousands of students prepare more confidently for their exams.
