The three-year simulation questions in the five-year senior high school entrance examination are more comprehensive, but they are generally used in the final review. The questions inside are generally formal exam questions, and there are always questions that have been recruited. If you win the championship easily, the questions in it are novel and suitable for ordinary practice. However, if you buy a lightweight to win the championship, you must be optimistic about the printing times inside, and look for the one that is closer to the present year, preferably 20 10, because the topics of the new edition will be changed compared with the old edition, and the topics changed by the publishing house are generally hot topics. You can choose according to your own situation. You'd better look at these two books and compare them before you buy them.
