To tell the truth, Shandong's body shape is relatively new, not an old-fashioned topic, especially science. Generally, you don't do many similar questions, but in the final analysis, it is also basic knowledge, so master the basic knowledge first, and then find some flexible questions. For flexible topics, the best and most effective way is to love mathematics. For the problem of improper time, first of all, you should remember a *** 12 multiple-choice question and four fill-in-the-blank questions, which is not much to say. Try to finish it in half an hour, 45 minutes at most, usually more than 45 minutes, which is a waste of time. In addition, pay attention to accuracy, score high in multiple-choice questions, and usually do more questions. If you are a senior three, there will be many mock exams and classroom exams next semester, so you should do them every time. Big questions, 17, 18, 19, can't be too difficult. Finish them calmly, pursue speed, even faster than a multiple-choice question, and finish them in half an hour to ensure accuracy. You will get a score. You will know what kinds of problems there are in the later stage of senior three, which are basically fixed, trigonometric functions, series, solid geometry, but pay attention to series. 20,21is a bit difficult, and it will only take half an hour to stabilize.
