I have personally experienced the college entrance examination. I bought "Examination Questions Survey", which is available in all subjects. Mathematics is published in stages with detailed explanations. There are several kinds of topics from foundation to promotion, some of which are the wrong sets of top students in the college entrance examination, some are the sprint one month before the exam, and so on. In senior three, I was poor at math, and sometimes I got 890 points. I put the wrong questions in every exam and practice into the wrong set, and I take time out to do them repeatedly every day when I study by myself, summing up the methods and rules. This method is very useful. The most important thing is that you read the textbook first and understand the principle. You must remember this principle before you can use it. Moreover, be sure to ask more questions. If you can't, don't be afraid of losing face, otherwise, there will be more and more problems that won't accumulate, and there won't be too many in the end. I don't know where to start if I want to learn. You know very well that it is not shameful now, but it is shameful to fail in the college entrance examination. Finally, I got a score of 135 in the college entrance examination, which made great progress. Finally, I wish you to be the first.
