Don't be afraid at first, no matter how many rounds you review. You have to have your own rhythm, and the foundation is not solid. Then you can hold the determination to turn over the book, let the teacher turn around when he sees you, and master the foundation that you didn't master in the first round. There are still 99 days, that is, more than three months. Six subjects, chemistry and physics, which one do you choose? There is still a whole month, that's enough. What you have to do now is to have your own review rhythm. If you can't keep up with the teacher's guidance, don't try hard to follow, because it is the second round, and it mainly talks about the sea, not knowledge points. In the second round of dealing with teachers, you can do it at a glance. If you can't do it, give up. When he talks about this problem, he will ask very hard. Is this ok? If the teacher asks you why you don't do it, you can simply say that you can't do it. There is also your classmate's first round, reviewing the main points and raising knowledge points, so let's take a look at such notes.

These are my suggestions for your current situation. The following is my answer to a similar question once asked by a classmate. You can learn from it. I also take physics and chemistry as examples to talk about my experience. I hope I can help you:

To learn chemistry well, you must be interested first.

Then write down all the knowledge points first and recite them. Finally, the main element family is used as a line to connect them into a knowledge network. Then you don't have to do any exercises, because those are all changed by pediatricians. Some knowledge points need to be memorized and some can be deduced. For example, H, the first reaction is not various chemical formulas, but the first element of the first main family of H. The common valence is 0,+1. Why? Because the stability of chemical substances is closely related to the outermost electron number, atomic radius and atomic weight. Therefore, H can exist stably in the form of H2 and H+. Corresponding H2, H+, hydrogen and hydrogen ions. H2 characteristics: flammable and explosive, and can react with most nonmetals: O2, Cl2, S, N ... H are usually active in chemistry and tend to be active metals, so they can replace some inactive metals, such as FeO and CuO. There are some nonmetals, such as carbon in carbon dioxide. The nature of H+, all positive ions have certain oxidation, so in acid, H+ can be reduced by active metals. H+ is special because it is an important substance to form acid. So the relationship with acid is a lot of reactions. In this way, when your knowledge points are gridded, you can write all high school chemistry textbooks from one element. This is to read the book thick first and remember more N knowledge points. Then read the book thin and become your own. Then come out of the book. After leaving books, full marks are not dreams.

There are as many knowledge points in chemistry as in physics. You can remember it by the periodic table. The chemical properties of the same main group elements are similar. So we can sum up some rules. Our chemistry teacher at that time also made up some jingles for us to remember some chemical phenomena. It is very helpful for you to think more and ask more questions about chemistry.

There is also an ultimate solution: it is a bit difficult: as long as you insist on doing the questions, think before asking questions when you encounter problems, and strive to achieve the same type of questions. What you can easily get in the third encounter is the truth, and diligence can make up for it.

Other subjects are similar, the first thing is to be interested, which has a lot to do with your teacher's guidance.

Again, the most important thing is that you should remember the knowledge points firmly first, which requires hard work, but also pay attention to methods, such as associative memory, associative memory and extended memory. The purpose of these methods is to connect the scattered knowledge points you receive into a network. So you can remember the prison, but it's hard to forget it.

Ask immediately if you don't understand. Even if you have to ask four or five times, keep asking until you remember. Don't be afraid of being annoyed by others, but by yourself. Mastering knowledge is a repetitive process.

In physics, it's easier to remember several laws, then start scribbling formulas, and finally pass a formula such as f = Ma = MV 2/R = MW 2r = GMM/R 2 (gravity) =Eq (electric field force) =Bqv (magnetic force).

When you use the acceleration formula as displacement or speed/time, this formula will be deformed.

And so on, and finally you derive all the formulas. Then I have the recipe, and I have it.

There are two other important things: conservation of momentum and conservation of energy. These two points should be deeply rooted in your soul. Try to understand. You can express it in your own language.

That's it. I hope you can draw inferences from others and gain something.
