The following is purely a personal opinion: the two teaching AIDS have different emphases. If you think you have a good foundation and fast calculation, but you can't grasp the test time well and are not skilled, then I suggest you buy 38 sets of senior high school entrance examination questions in important provinces and regions, which will be very helpful for you to be familiar with the test questions and improve your level. You can do this set of questions next to each other within a limited time, or you can do it according to the type of questions. Take mathematics as an example. ※. You can ask the teacher to recommend several sets of good questions for you to do well, or you can do them all next to each other, or you can do them for weak links. For example, if you feel that you are not good at geometry, you can do geometry problems, then sum up the law of solving problems yourself, and compare it with the method of doing problems told by the teacher to find out the routine of doing problems. If you feel that the calculation speed is not up, do the pure calculation questions on the test paper within a limited time, and pay attention to the mistakes. For example, multiply the unknown element by-1, forget to change the direction of inequality, and so on. If you just can't do the finale well, you can find the last question of each set of papers for 20 minutes and try to get it done. I believe it will improve all the time. But don't copy the answer as soon as you meet a question you can't, you might as well not buy it. If you really can't, you can ask your teachers and classmates. If you look at the answer, you can understand it first, then wait for five or six minutes to do it, and see how you digest the solution to the answer you gave. As for science, I don't know if you have a wrong textbook or a good textbook. If you do, you can sort out the problems you did wrong, but you can't do them for long, but you finally understand that you can solve them better. As for the key issues emphasized by the teacher in class; If not, and you think other schoolwork tasks are also heavy, forget it. Circle such questions so that you can easily find them when reviewing. The book "May 3rd" is a breakthrough, and it is a review topic compiled by the editor for you. Generally used in one or two rounds of review, it is comprehensive, but the number of topics is not small, and time is pressing now. If you buy it, you have to take into account the review and homework of other courses, and you can't finish it at all. Otherwise, you will spend a lot of time on it, which is not cost-effective, but the school will be fine, and the school teachers have their own plans. If you just have a poor foundation and many questions are at a loss, then after you buy it, you should choose the type that you can't do, pay attention to the methods given in the exercise book, or ask the teacher to help you tick a few questions every day, which will eventually improve. ※. Mathematics and science are both science courses, and the learning methods are the same, so we can learn from the above methods comprehensively. In addition, when filling in these "holes", do not neglect all other subjects, but take care of them. ※. The school teacher is very experienced in dealing with the senior high school entrance examination. The teacher's advice must be listened to, and the methods taught in class must be thoroughly understood. They can't "fight alone" by themselves, and they also ignore the teacher's plan when making their own plans. At this time, the teacher will bring out the most essential knowledge, so every class should be careful. At this time, the exercises issued by the school will be more targeted, so pay attention. If you are confused, you must communicate with the teacher more. There is still one month, every day, all progress is possible! Come on! Sincere blessing from a senior high school entrance examination "experiencer"
