How to get a high score in chemistry, high school chemistry exam is generally a few points to pass

It is necessary to memorize more reactions, memorize familiar with them, do more problems, and memorize models.

I am a chemical student,Chemistry MajorIf the chemistry major of this school is an ace major, then its score must be higher than the school score line, if it is not an advantageous major, then you can generally go to this major if you pass the school score line.

University of Science and Technology of China, Nankai University, Jilin University, Fudan University, Xiamen UniversityShanghai Jiaotong University, Nanjing University, Zhejiang University, Fuzhou University, Tianjin University, South China University of Technology.

Chemistry at universityIt has more depth and breadth than high school chemistry, but to be honest, there are really many courses, and if you don't study seriously, you can really only learn the surface, and you can cope with exams.

In addition, I like the laboratory class the most, not only can I test my learning results, but also master a lot of experimental skills, and many experiments are very interesting, such as the analysis experiment can always see the magic color change, organic experiments can synthesize various drugs.

First of all, there are the four basic chemicals, which are:Physical Chemistry, Organic Chemistry,Inorganic chemistryand analytical chemistryIn addition to this, there are four major chemical experiments, and of course, there are also learningStructural Chemistry, Fundamentals of Chemical Engineeringand other compulsory courses.

Chemistry majors can be engaged inTeaching professions, researchers, chemical plant technicians, pharmaceuticals, etcHowever, most students will choose to continue their studies in graduate school, and many students will choose to be a chemistry teacher, and the rest of the students will find their favorite jobs at the campus job fair.

Overall, the chemistry major is still very good, if you are interested in chemistry, you can choose this special section to study, I believe you will be able to, I wish you a successful college entrance examination.

There is no specific score requirement; Based on the score of the paper, A, B, C, etc. are delineated according to the cumulative proportion of the closest % of the actual number of examiners.

Taking Zhejiang Province as an example, the high school examination results adopt a grading system, with five grades: A, B, C, D, and E, and E is unqualified. Based on the paper score, A, B, C, etc. are delineated according to the cumulative proportion of the closest % of the actual number of examiners, and the proportion of E is not more than 5%. The grades of students in the internal senior class and the internal vocational class that have been approved are separately delineated.

Implement a system of individual performance diagnosis and report. The grade level and the individual score diagnosis report can be queried by the Zhejiang Provincial Education Examination Institute**, and the grade level will be provided to the candidate's school. Ordinary high school students who are transferred from other provinces, return to school after going abroad for study and exchange, enlist in the army, or are admitted to the university in advance, and who do not take the examination subjects and need to be recognized for their grades, shall be implemented in accordance with the relevant documents of the department.

The current academic examination system has a full score of 70 points, so it is 42 points to pass. However, there is no such thing as a passing grade in the strict sense, because the grades are divided according to the proportion of the number of people. Maybe you scored below 42 but still passed the exam.

All students who rank in the bottom 5% of the number of people who take the exam will be judged as failing and will be required to take the subject again next time. In both cases, there will be one chance to retake the exam, and the fee for each exam is 20 yuan.

Chemistry is generally a perfect score of 100 and a passing grade of 60.

1. Chemistry requires many aspects of ability: memory of fragmented knowledge, number crunching, descriptiveness, inference and analysis from known information, etc. However, the ability requirements in these aspects are not high, in terms of the richness and fragmentation of knowledge content, chemistry is far inferior to biology, and in terms of the amount of calculation and the difficulty of analysis, chemistry is also lower than physics and mathematics.

2. Therefore, as long as your ability is relatively balanced, chemistry questions will not become the biggest obstacle. On the contrary, if you are very poor at one area, chemistry questions that test that area will give you a headache.

3. Learning chemistry is really changing your knowledge system, and the changes in it want to change from two-dimensional to three-dimensional, and then you can suddenly look at everything you have learned from a higher perspective.

4. For example, the concept of acid and alkali, for example, metathesis reaction: when I was in junior high school, the teacher told you that the metathesis reaction generates insoluble matter, water, and gas, and the teacher told you that it is actually generated by non-electrolytes.

5. In the study of chemistry, the first method is to accurately grasp each concept, summarize some counterexamples that are often encountered, and combine the two with each other. For example, if there is a non-metal formation, it must be a covalent compound, then it will be found that ammonium chloride is an ionic compound composed of non-metals.

In this way, the concept of covalent compounds can be fully grasped. The second point of the question, you can write the steps you do next to the test question, whether it is chemistry or mathematics, physics, so that you can really know the reason for your mistakes when correcting, and at the same time, you can also talk about correcting some of your bad habits and improve your scoring efficiency.

Taking the textbook as the main line and carefully reading the textbook is the foundation of learning chemistry well. To this end, we must be good at reading textbooks, so that we can read before class, read carefully after class, and often select reading, etc., and not only pay attention to the main content, but also do not ignore the small print part and some charts and optional content, because digging into these internal shortcomings will help deepen the understanding of the main content and broaden the scope of knowledge. When reading carefully after class, you should read and remember while thinking, and strive to solve all the unsolved problems in the preview and listening to the class.

Regular reading refers to selective reading of important or difficult to fully comprehend content. At the same time, through various forms of reading, it also helps to improve self-learning ability.

Junior high school chemistry is a natural discipline based on experiments, chemical concepts and laws are drawn on the basis of experiments, and there is no chemistry without experiments, therefore, in order to learn chemistry well, we must pay attention to experiments, remember the names of commonly used instruments, be able to draw graphics, understand the structure, master the use of methods, and carefully observe and think carefully about the 85 demonstration experiments on the textbook, and must do 10 of the 22 student experiments that must be done by ourselves.

After each unit test, we must conduct a self-evaluation and check to find out the results and existing problems, especially to analyze what is the reason for the loss of points, how many points are accounted for such as 6 points, of which 2 points are lost if you are careless, 2 points are lost if you will not be able to review, and 2 points will be lost if you do not review comprehensively, and then analyze why you are careless and will not, find out the reasons for future learning, and it will be beneficial to persevere. Achieve continuous improvement of their non-intellectual factor abilities.

If you want to get a high score, then you have to study hard, so these are all issues that need to be paid attention to. And you must find a learning method that is suitable for Zen Hongxian, and at this time, you must recite some chemical congratulatory beats, and you must have a good foundation, so that you can get high scores.

1. How should I study to get a high score?

Many people may think that chemistry is very difficult, and they didn't study chemistry at that time, because they felt that they couldn't learn it, so they chose to study liberal arts at that time. But you must find a learning method that suits you, and I think that chemistry is also very interesting. Everyone must memorize chemical formulas, and they must memorize some knowledge points in daily life, because these knowledge points must be memorized, and they will be tested in every exam, so everyone must lay a good foundation for themselves.

2. What issues do we need to pay attention to?

And we must have a good learning mentality, there are some people who are usually very nervous in life, because these students are too concerned about their grades, so they can't play normally during the exam, so their grades will be very poor. Therefore, you must find a method that suits you, and you must have a good attitude in life, and you don't need to be so nervous when you take the exam, as long as you study hard in life, then you can get good results.

III. Conclusion. If you want to get a high score, then you have to study some difficult questions, and you must pay attention to checking your test papers when you take the exam. When you take the exam, you must pay attention to the time to solve the questions, and you must control your speed in life.

If you want to improve your chemistry scores, you can also seek help from your teachers.

The first is to be interested in the chemistry of Bei Xian, and then memorize more chemical equations, so that the imitation may get a high score, and the other is that when learning chemistry, the party also needs to master the introductory skills and master a learning method suitable for themselves. In addition, you need to brush up on the questions more, so that you will improve your score.

When studying, you must pay attention to memorization, you must master the learning methods and skills, memorize the periodic table of chemical elements, and memorize chemical equations well.

You should listen carefully during class, and if you encounter any questions you don't understand, you should ask the teacher immediately, and you can also make up lessons on weekdays and weekends.

First of all, you must listen carefully in class, it is best to take notes, and secondly, ask the teacher for advice.
