① Thoroughly organizes the key concepts covered in the textbook, and includes textbook verification questions for each concept element.
② Only problems with a high probability of appearing on the exam are selected based on analysis of past exam questions, and twin problems are presented to enable repetition and review.
③ Design a process to acquire descriptive methods according to difficulty by presenting descriptive questions with a high rate of appearance in a separate corner.
④ Problems with changing conditions or shapes or difficult transformations are structured by level and difficulty to improve problem solving ability.
⑤ The problem-solving skills developed through previous exam questions can be applied to more difficult real-world problems, presented in two sessions.
⑥ As the number of questions in textbooks increases, separate thinking skills problems in textbooks are being created.
⑦ Final rehearsal with multiple choice/descriptive questions expected to be asked so that you can finally check your weak areas.
⑧ Only the problems that many students make mistakes on and that take a lot of time are collected separately and provided as an appendix.
