If you want to be an exam-oriented teacher and bring out a good class, I recommend you to brush more questions, do more books such as the five-year college entrance examination and the interpretation of Longmen questions, improve your problem-solving ability and share your problem-solving ideas with students.

If you are not a senior three, I suggest that you teach students more guiding thoughts, recommend what is mathematics by R. Crown, others, such as From One to Infinity, and some books on the history of mathematical thoughts, so that students can understand the real mystery of mathematical thoughts and their mathematical literacy is very helpful.
