Wang Houxiong's is better, and high school teachers are also recommending it to students. There is also a handbook of important and difficult questions, which is very useful, mostly college entrance examination questions and difficult questions, as well as easy-to-mistake questions. It's very good. I recommend it to you. I wish you a happy study, come on! Learning to sail is also good, and there are many problems. However, you are now in the second grade, especially the compulsory courses 3 and 4, which are more difficult. Some people can't get into high school. I suggest not to be too eager for success, take your time, and don't focus on the topic from the beginning. There are no teachers in high school, and maybe they don't understand some basics. It's good for you to buy Wang Houxiong or learn to sail. You can read the handbook of heavy and difficult points in high school. I still like you. I wish I could be as serious as you. Hey, come on, I like you.
