The first choice is "three-year simulated five-year college entrance examination", which I personally feel is good. At first, math was not very good. Later, I spent a month studying by myself in the evening, all of which was used to write Math Five Three. After about 80% completion, I developed a sense of touch. I am a 20 13 science candidate in Henan, and my math score is 134, which is beyond my expectation. I highly recommend "53 Mathematics", but you should make good use of it. I suggest that you not only delve into difficult problems, but also make good use of the wrong questions after practicing them once, and it is best to read them again. If you complete about 80%, you can reach the level of simple questions without losing points, intermediate questions with more points and difficult questions with one point. But the most important thing is your personal efforts, come on!
