Start by building self-confidence, believe in yourself, then build the basics and then practice.
Don't be afraid of difficulties, if you don't understand, you have to ask, if you encounter many problems, solve them, and naturally improve.
-
My experience is that if you do a good set of mistakes, keep revisiting them, and make inferences, it means that you really know how to do that type of question.
-
Start with the basics.
-
Personally, I think it is much better to start with the calculation method, and it will be much better to learn other aspects if you are familiar with all kinds of calculations. This is purely a suggestion and learning varies from person to person.
-
First build self-confidence, don't give him difficult problems, start with the simplest. Then do more example questions, not more, only right.
-
Little Brother: The key is that you have to be willing, everything is not difficult.
Start with the basics. If you can do math in junior high school, then pick up the math textbook of the first year of high school, start from the first chapter, go through it little by little, ask your classmates and teachers about the knowledge you don't understand, and do every exercise, you have to know it, and you have to get it thoroughly.
Note this:
First: When it comes to the problem, you must think about it first until you really can't do it, and then ask people, don't ask if you can't see it.
Clause. 2. Don't buy comprehensive review materials at the beginning, don't do comprehensive questions and college entrance examination questions, it's best to do after-class exercises and basic individual knowledge questions.
Third: After reading (listening) understanding the question answer, don't end it, generally speaking, look at the question solution to deal with it like this: the first time:
See if he did it, the second time to see how he dealt with each step, the third time to think about why he did this and not that, why he used this formula instead of that, the fourth step, do the problem again, or ask yourself, if you encounter this problem again in the future, will you do it? Step 5: Is this method the only way to solve this problem, is this problem the only way.
Fourth; Slowly your level will be higher, and then do a more comprehensive question, this synthesis must be the topic of the integration of your previous knowledge points.
You can experience the words above, and practice them to have extraordinary gains.
-
Understand and memorize formulas and theorems first, classify them, and establish connections between them; Finally, do a few more practice questions for each formula to consolidate and deepen your understanding.
-
If you have to talk about shortcuts, you can first look at the college entrance examination papers, prescribe the right medicine, see what type of questions are in each part, what knowledge points are involved, and then carry out special training, do not pass the practice, and be sure to understand each one.
-
Do more basic questions, memorize formulas, read more example questions in textbooks, and ask the teacher more while you are not nervous in high school 2, otherwise you will have no chance in the third year of high school.
-
There are no quick skills for learning science questions, just rely on you to buy exercises to practice, and then summarize the ideas for doing various questions, so that over time, the results will naturally improve.

Based on my previous process of studying mathematics, physics and chemistry (each subject has several perfect marks), and the results, I have come up with the following experience: I hope it will be helpful to you.
I believe that learning mathematics, physics and chemistry should be done from books to exercises; From easy to difficult; From simple to complex; From quality to quantity; From slow to fast. (i.e., the "five-gradient").
First of all, the so-called from books to exercises, we should "eat thoroughly" the books, be able to understand the above knowledge, and be able to memorize by heart, if we can't memorize it for a while, we can put it aside a little (by doing exercises to familiarize ourselves with the knowledge points), and then do some related question types according to the knowledge points.
When doing the questions, we should go from easy to difficult, that is, we should pay attention not to blindly do too difficult questions first, we should first do some simple questions, the purpose is to consolidate the knowledge points, familiarize ourselves with the knowledge points, and then slowly become more difficult questions. This serves the purpose of strengthening.
As for going from simple to complex, that is to say, we should first do some questions that contain a single knowledge point, and be able to summarize the knowledge points of the question, and then slowly strengthen the depth and do the questions that contain multiple knowledge points.
From quality to quantity, that is, when we start, we should focus on quality, not quantity. Even if we can only do one question a day, as long as we get it right and understand. We also have something to gain; But if you do a lot of questions in a day, all of them are wrong, and you don't master any of them, then it will be in vain.
Only we can guarantee the quality of the questions, and after a certain degree of accuracy, we can slowly change to the quantity.
As for the slow to fast, it is an auxiliary practice for the exam, and everyone knows that when it comes to the exam, time is very tight. Time is like money, every minute and every second is very precious. In normal times, we should strengthen our training, ensure accuracy while slowing, and then slowly improve the speed in all aspects.
Finally, it reaches the present that is both fast and accurate.
As for other information, books alone are certainly not enough. There must be information. At least two books (you can add more if you have enough time), one is a shallower, single-aspect knowledge book, and has a question type to consolidate knowledge points; The other is a book on the type of questions for comprehensive training.
Finally, you can make a book of mistakes and a collection of questions. Error set is used to classify the questions you did wrong, summarize the reasons for the mistakes, summarize the knowledge points, and open the knowledge points to master? After you really grasp it in the future, mark the question or delete it directly.
As for the collection of questions, it is used to record the classics, typical topics. Therefore, the study of science can be summarized as "five books" (books, follow-up exercises, comprehensive exercises, error books, and collection books. )
If you can do "five gradients" and "five books". I believe that it will no longer be a problem for you to learn mathematics, physics and chemistry well.

The key is to make good use of your time and be well-organized, and it is recommended that you focus on mathematics during your evening self-study time, and study liberal arts the rest of the time. It's best to lay a solid foundation from scratch, after all, it's not yet the college entrance examination, it's still too late, and there is still a summer vacation for you to work hard.
-
In fact, liberal arts math is very simple, just memorize the formulas.
What do you think about when you were in junior high school? You'll feel like you're learning nothing! Because it has passed, I know how simple it is.
You can solve the equation, take a look at the formula of the function, and then learn to find the derivative, middle school mathematics is OK, no need to deduct the problem, learn the most basic, 100 points are no problem.
-
Mathematics only needs to have a deep understanding of the definition, and then summarize some methods, preferably to understand mathematical ideas, then it is OK.
-
I'm also a liberal arts student, hehe, but for some reason, I like mathematics very much, but for people who don't like it, in fact, there are many dead ways to die, many of which are based on formulas, and if you really can't understand it, just memorize the formula directly In fact, the question type has not changed Come on.
Geography is not easy to make up, politics can be, history can be sorted out according to the age, but geography is not a very good way, I used to learn geography is also a good hand, there is no other trick, look, look at the map, and then look at the explanation, you have to like the map. However, don't be frustrated, it's still too late to read the book now, read all the previous geography textbooks, it's best to buy an authoritative point of the "geography atlas", often flip through it, the key point must be remembered, there is really no good way to only rote memorization, I wish you progress in your studies.
Look at the table of contents, generally understand what trigonometric functions, solid geometry, vectors, sequences, etc., and then correspond to many different types of questions, slowly try to understand each type of question, read the answer if you don't understand, step by step analysis why you do this, that is, the solution idea, if you don't understand, ask the teacher to solve the problem.
It is very important to have a correct, efficient and suitable learning method to help us improve our learning efficiency and thus improve our academic performance. The time invested in the language subject is relatively small, because it is difficult to improve the language in a short period of time, and it mainly depends on the accumulation of ordinary time. Mathematics is important to persevere, and it is necessary to repeatedly study the college entrance examination papers over the years, find out the types of common examination questions, and discover the distribution of knowledge points and examination rules. >>>More
If you are interested, you can learn, and you are still learning theoretically. High school art, not science, is too much for flexible solutions. >>>More
It's definitely not okay to cramm for a while, so use the summer vacation to make up for it. >>>More
