Because of my poor math foundation, I bought this handout for reviewing the college entrance examination of Star Education. It follows the trend of college entrance examination and is edited by hundreds of famous teachers. It is an all-around book that can solve all problems in one round of review. Together with the exercises of Zhihong series "Ten-year College Entrance Examination", it feels very suitable for people with poor foundation like me. If the foundation is good, you can use Tian Li Sanba set or Longmen special topic. If you want to engage in sea tactics, you can use inscriptions, which are especially suitable for physics and other sciences. I don't have this, but I bought it in junior high school. It works well. Let me taste the sweetness of the sea tactics.
