If you think you still have talent, but you didn't attend class before, and your knowledge is backward, which leads to poor grades, then you can still be saved.
There is a shortcut to improve your grades quickly, but you can't get high marks (for example, 130/ 150). All methods will eventually return to textbooks. Knowing all the knowledge points in the textbook can guarantee a high score in the math exam. Let's talk about this shortcut first
First, take a comprehensive test paper (that is, the test paper of all the knowledge of mathematics in high school), and then turn directly to the big questions behind. Refer to the answer and fully digest the steps and knowledge points involved in solving big problems. At the same time, take a good look at this section of the book in order to fully grasp it. Do more such big problems and accumulate problem-solving skills and experience.
This step can ensure that the big questions are not left blank and you can score a little. If the situation is good, you can even work out the answer. However, under the difficulty of the college entrance examination, it is still difficult to make a question.
The college entrance examination is very comprehensive, and often a topic will have many knowledge points connected in series. If one of them doesn't understand, they can't completely solve a problem. Therefore, we need to take the next step.
The second step is to conquer the remaining knowledge points. In fact, there are many knowledge points to master in the first step. Like solid geometry, trigonometric function, inequality, sequence, function, elliptic function, probability and so on. After the first step, I have learned all the main branches of mathematics. The next step is to finish the rest and build a building. Only by mastering everything can we not miss. There is often only one solution to the problem of college entrance examination. You must be familiar with all the knowledge points before you can string together the conditions and get the answer.
Therefore, the second step is the most complicated. At this time, you should do more questions such as filling in the blanks in front of the test paper. In particular, multiple-choice questions need some special problem-solving methods and discrimination methods, which are very valuable ideas in solving problems. You can only answer well if you have an idea.
Some people have mastered all the knowledge points and taken the exam seriously, but they still can't get high marks. At this time, the third step is necessary.
The third step is to achieve mastery. This requires long-term contact with mathematics and serious reading. Still think more when doing the problem and understand the connection behind each condition.
Another point is the estimation of the result. This is also a very important point. Just like the sixth sense, of course, this is a sixth sense based on science. Usually, if you solve more problems, you will naturally predict the general appearance of the results.
There is always another point, sensitivity to various conditions in mathematics. For example, in geometry, when two sides of a triangle are 5 and 12 respectively, it is natural to wonder whether the other side is 13. This triangle is a right triangle. The topic is not given directly, you can try to ask. If the right angle is proved, there is another condition. And this condition is often the key condition.
