First, mentality! Even if your previous foundation is not very good, don't think too much, don't give yourself pressure, don't blame yourself for not doing well in the exam, and don't think so, otherwise it will affect your learning resilience and disturb your thoughts. Worrying too much in the process of learning will make you lose sight of the hope of progress. We must strengthen our confidence and not waver: I want to improve my grades, and I have sufficient information to improve! Mentality is too important, so I put it first;
Second, you must improve your self-control. If your self-control ability is poor, I think no amount of ideas will be in vain. Only by improving self-control can we persevere and get twice the result with half the effort. I hope you can understand.
No matter what your foundation is, I suggest you keep reading textbooks every day. You can prepare a notebook and make a very detailed study plan for tomorrow with reference to your own curriculum before going to bed at night, mainly to determine what to do in your spare time and what kind of purpose to accomplish, such as: studying by yourself at noon and reading the first chapter of mathematics, and of course you can arrange two courses to achieve a harmonious state; How long does it take to relax at lunch, and then arrange study courses, etc. , and list all the free time of the day when the teacher is not in class. Don't be afraid of trouble, just stick to it. At the end of the day, remember to reflect on whether your planned goals have been completed, so as to make progress! Trust me, it's not a waste of time. I didn't get many firsts in mathematics at school before, but I always got the first place in my class. I don't want to show off. I just want to say that I can help you, and I want you to believe that good habits can guide you better.
Fourth, you should also have the skills to review textbooks. Don't turn pages blindly. This will not be very effective, but will make you feel very useless, and it will be annoying after a long time. How to learn? You should know that every textbook has a catalogue. First, I ask you to write down the table of contents. For example, there are several big chapters in the textbook of senior two, and how many sections are there in each chapter? This is the first step, and then try your best to read the most important information in each chapter, especially the formula. Finally, I can successfully tell the important information of chapters, sections and paragraphs of a book in order, as well as the most typical examples corresponding to important chapters. If I have the ability, I can tell a whole question with typical examples (but this estimate is more difficult for you, so try to be the first one). I taught one of my classmates this way. When she thinks she has done it, let her tell me. This is a way for me to strengthen my memory.
If you insist on doing the above two points, then you should do exercises and combine them with reference materials. Because the foundation is not very good, I suggest you do exercises selectively and give up if it is difficult, but the real exam paper is also problematic and must not be completely blank. Look at the questions carefully and write down the formulas you can think of when you see familiar knowledge points, otherwise you will get nothing.
Sixth, it is very important to pay attention to reading keywords when doing problems. This technology should be mastered by doing more exercises, not much to say;
Seven, when doing multiple-choice questions, we should learn to exclude (mainly using counterexamples), disproof (mainly verifying the correctness of the results), drawing, comparison and so on. I often use this method and the effect is quite good;
Eight, don't look at the answer immediately after finishing a question, otherwise it is easy to develop your distrust of yourself, delay time and increase the error rate. And the exercises you did today, watch them again before going to bed at night. Educators emphasize repeated recitation, which is very effective;
I suggest you attend some basic remedial classes. Of course, if your financial conditions permit, remedial classes will also help to some extent. I think the notes in the remedial class are very useful. It's all summed up by great men. It's really good. I just read it repeatedly and learned a lot, really;
Ten, usually play less mobile phones and computers, these things take too much time and brain power, you can leave me a message if you have any questions, I hope you can improve your grades as soon as possible!
