How to learn chemistry, physics, and science well in the third year of junior high school

Chemistry: Mainly chemical phenomena, chemical formulas and standardized use of instruments. If you take notes in class, you should be able to memorize them, and if you want to expand, you can go to class outside of class or do some practice problems. Remember.

Not only in junior high school, but also in high school, it is very important to ask the teacher, if you don't understand something, just ask, don't care about being shy or anything. It doesn't matter if you don't understand even a chapter, just ask, otherwise you will regret it after the high school entrance examination.

Keep up with the teacher in class, unless you're confident that you know everything, but it's best to think about the score.

Physics, the most important thing is the formulas and concepts, although understanding is the best way. But if it doesn't work, you have to retreat to the next best thing, and you have to force your back! It's important to ask the teacher.

The most important thing in doing science papers is to be careful, don't step into the trap, but be moderate, don't send any grading questions and be entangled there for a long time.

High school physics and chemistry are actually very simple, the key is to read the things in the textbook thoroughly, don't think that the teacher can understand what the teacher says, in fact, you are confused.

Tell you a simple, stupid way, memorize all the physical formulas, laws, axioms, and chemical equations, or you can say it without thinking about it, and then do the questions wildly, physics and chemistry do 5000 questions each, it should be about the same. Make one roll a day. And most importantly, don't look at the answer when you do the question, looking at the answer is equivalent to not doing it.

I'll just talk about physics, because chemistry is almost gone!! Hehe.

First of all, you have to be familiar with these formulas and know their physical meaning, in fact, this is also a method of physics for your high school students, that is, the understanding of physical meaning! I was the representative of the physics class in high school, and the physics score was stable at more than 110, I think that after you memorize the equation and understand the meaning, it is your spatial imagination ability, you should imagine the motion process of the object, and learn to integrate it, such as the connection between electricity and mechanics, etc., you can meditate and reflect after doing the problem to exercise! Do the right amount of questions!!

I also studied physics in college, and only then will you realize that the physics we learned in middle school are all the same!! Hope it helps!!

Listen carefully in class. If you don't understand, take the time to ask the teacher or classmates. Frequently turn to the textbook to understand the meaning of key sentences. In addition, I want to finish it! If you won't, just ask! Nothing to be embarrassed about. Finally, practice makes perfect.

You have to sort out your mistakes every time, follow the correct ideas, and find at least three exercises that are similar to them.

Summarize and classify yourself. It's going to be hard at first, so it's good to get used to it.

Chemistry should be pre-studyed, and you should not be deserted in class.

Physics should be more problematic.

This shows that your foundation is not good!

A lot of people are looking for ways to learn, but they don't grasp the basics. People build houses to see the base is low, only the base is low, how high you want to build. Therefore, the most important thing in mathematics, physics and chemistry in the third year of junior high school is to listen more, watch more and practice more.

Only then will you be able to learn how to learn that works for you. Hope it helps.

Hehe, junior high school physics and chemistry will make you like this, and I guess you will study literature in high school.

If you can't do it, think more and try more methods. When you really can't do it, ask your teachers and classmates, but you must figure it out without thinking, so that you will be able to solve similar questions in the future!

Be persevering and don't give up at the slightest setback. When you conquer it, your sense of accomplishment will make you even better!

1.Preview. Before class, read the content to be taught in the next section, mark the things you don't understand, and focus on listening in class, which can improve the efficiency of listening to the class.

2. Attend lectures. Listen carefully to the class, write down the key points, pay attention to absorbing and understanding in class, and ask questions immediately if you don't understand. (If you don't have time to prepare, be careful to make good use of your class time.)

3.After class, you should organize your class notes and sort out the knowledge you have listened to and memorized in class. 4.

Do more questions after class. If you want to learn physics and chemistry well, you must do more questions, and you must know each type of question. It is necessary to sort out the various types of questions with regulations.

Summarize the method of doing the question and do the question finely.

In fact, junior high school physics and chemistry are relatively simple, as long as you pay attention to the class, take notes carefully, go down to do exercises appropriately, and then look at the textbook more, try to be familiar with the textbook, because the junior high school exam is inseparable from textbook knowledge. If you still have the energy, then do more practice (questions)! Because you remember a sentence, science courses can't be seen, and you have to do a lot of practice questions to consolidate your knowledge!

In this way, I believe that your physics and chemistry will go to the next level!

Listen well in class and do targeted exercises!

Nothing men! As long as you listen attentively, do more questions, and think.
