I m a junior in high school and how to study biochemistry well

There are not many skills in learning biology, because biology is basically a test of some conceptual questions, and the most difficult thing is about the free combination of genes and the implicit nature of the determination of organisms, which is good as long as you master the rules, and the rest will test your memory. There are many laws in chemistry, such as the properties of inorganic matter as long as it is summarized according to the periodic table, memorized by heart, the key is the law, and the law of organic matter is not as clear as inorganic matter, but it is also traceable, we can summarize the knowledge of the big question, the memory of a small part of the special knowledge to master, and there is also a question to do, I am not in favor of doing the question sea tactics, the appropriate one is enough, good luck, the college entrance examination is smooth.

I think these two subjects are mainly memorized, especially chemistry, and the test phenomena and chemical equations are more memorized, and the calculation of the points is almost the same; Be careful when remembering biology, I feel that biology questions are full of traps, so be careful whether you remember or do the questions, as for biology calculation questions, there are fewer question types, I believe you can find some time to study it specifically.

Preview by yourself first, listen carefully in class, review in time, and do more questions.

But if you just need to pass the exam in order to cope with the exam, listen carefully in class, read and understand the content to be tested before the exam, and you can pass hehe.

It can be said that biology in the third year of high school also belongs to science, which is relatively difficult, but when studying, you still have to make a plan, find out your weak points, and focus on it.

Biology in the third year of high school is actually very good, learning, as long as you can sign up for the first time, biology in the third year of high school is still relatively simple.

1. Arrange the order of answering.

Go through the whole volume first, from front to back, easy and then difficult. Don't be chaotic in trouble, don't panic when you encounter new, and respond calmly. If you encounter a question that can't be answered for a while, sometimes it's not that you won't, and the rock is overrun inhibition, don't drill the horns, otherwise waste time and brainpower, rather than casually answering, it is better to put it aside for the time being, and the casual answer is equivalent to admitting the deduction of points, at this time, the first thing you can do is done, and then you can tackle the problem after doing it right, of course, you must avoid doing this question, thinking about that question, and multitasking, so that it is difficult to ensure the speed and quality of thinking, and it will affect the normal play of conventional questions.

Two: Inspection. After completing the questions, you need to check, the exam is very comprehensive, there are many question types, there are many contents, and the thinking excitement center is constantly changing.

Generally, go from the back to the front, first check the whole test paper to see if there are any missing questions, have you answered all the questions? Gnaw on the problems that have not been made, and finally check the aspects that are easy to make mistakes, such as whether the question requires the writing of chemical equations, chemical formulas, electronic formulas, structural formulas, etc., and the products of esterification reaction do not omit "water", and the products of polycondensation reaction do not omit "small molecules".

3. Time allocation skills in the examination room.

In the face of the exam, look at it before and after, how many questions there are, which questions are familiar, increase confidence, and allocate time (in the unit of the entire question type), leave enough time to think deeply, and strive to get an advantage score, reflecting the strength of the individual, it takes about 70 minutes, and the remaining 10 minutes or so are used for inspection. Once the problem cannot be solved within the estimated time, you should put it aside for a while, do the following questions first, and do not spend too much time entangled in a problem, that is, if you encounter a stuck, let go as soon as possible.

Fourth: improve the speed and accuracy of problem solving.

The exam has a certain degree of difficulty, the weight is heavy, the time for answering the paper is limited, and the speed is very important to complete the questions. For example, carefully review the meaning of the topic, do not rush to the end of the question, be sloppy, must understand the meaning of the topic, and pay attention to the key words, words, and sentences in the topic. Thank you.

Nowadays, many students want to know how to learn junior high school chemistry well, and they don't know where to start when they learn this course, this problem is very difficult for them, now let's find out how to learn junior high school chemistry well!

Chemistry is a basic discipline that studies the composition, combination, and change of some special substances, and it has a very great role in agriculture, society, science, etc.

How to learn chemistry well in junior high school?

1. Understanding. When learning these courses, you need to understand the concepts and theories, which are necessary knowledge points for learning all courses, and you also need to have a very good foundation, generally these concepts are expressed in very simple sentences, so you need to grasp the key, and then memorize.

For example, catalysts, a concept that generally requires comprehensible memorization such as sum, equality, and so on. These concepts not only need to be correctly understood, but also need to be used correctly, and generally speaking, chemical professional terms refer to some sentences expressed in the experiment, such as element symbols, etc., which are all content to be fully mastered and used correctly.

2. Structure. In this course, it is necessary to know the structure of the object under study, which is directly related to the nature of the object under study, and the nature will affect the state of existence and use of these substances, so it is necessary to grasp the structure of these substances to make judgments.

For example, oxygen, you need to think about what it is made of and what space it can exist in, what kind of substances will cause abnormal reactions, and under what circumstances it will cause harm to the body, etc.

3. Test. In the study, the test accounts for a large proportion, the students need to carry out their own work, need to know how to separate, purify, identify, etc., in the analysis of the need to draw certain conclusions through some specific means, in the use of the instrument needs to be careful, in the process of doing as correct as possible, the results should be more obvious, in the teacher demonstration needs to be patient observation, a comprehensive understanding of its principle, so that they can carry out the test without error.

4. Learn the law. When studying, you need to find your own learning style, there are many contents in these courses, so if you don't study properly, your score may drop, and it is very important to find your own learning style.

The above is about how to learn chemistry in junior high school, I hope the above content can help you when students learn chemistry.

The foundation of junior high school must be done well Anyway, the book in junior high school is just like that, take the time to take a good look at it, and the high school will naturally be easy to solve It is still a book to read the content of the book and understand the content of the book thoroughly in the question, you can't do the problem before you have read the book, it is useless After a book is thoroughly understood, you must use your brain to do the problem and be good at finding ideas for solving the problem.

Listen carefully, take detailed notes, do more questions, and biology will be fine.

High school biology is mainly to read more knowledge in books, and the key is to find spare time to memorize it, do the questions well, not more, and understand each question.
