These things are easy to find in bookstores, such as five-year and three-year mock college entrance examinations, 38 sets of Tian Li, and star series. Just go to the bookstore and you will know. Personally, I think it is better to buy a five-year and three-year simulation of the college entrance examination, and the explanation and classification are very good. I use it. In addition, online, many websites also have these problems, such as the education channels of Sohu, Sina, Netease and other websites, which are easy to find. In addition, you can also find a lot directly with Baidu search.
