How to improve high school biology and chemistry quickly in a short period of time

The study tasks in the third year of high school are relatively heavy, so the method is very important. For science studies, note-taking is key. Notes include not only class notes, but also a notebook.

In the class notes, you should write down the key knowledge points and the points that are easy to make mistakes, and the wrong question book is to write down the questions you have done wrong, and write down the relevant knowledge points, why you are wrong and the correct way of thinking. Take it out every week or every month to review, delete those questions that you have already learned, and make the wrong question book thinner and thinner, so that you can make up for the loopholes in learning in time.

And when studying chemistry, summarizing is especially important. There are many students who complain that the chemical knowledge points are very miscellaneous and scattered, but as long as you summarize them, you will find that there is actually a connection between the knowledge points, and the most fundamental thing is the knowledge involved in the periodic table or the basic chemical properties of each element. Secondly, it is not difficult for everyone to find that the types of questions on the simulation papers in each district made in the third year of high school are actually similar, and the test points are nothing more than redox reactions, basic calculation methods, physical and chemical properties of elements, and chemical experiments.

The essence of the sea of questions tactic is not to do all the questions, but to summarize the questioner's thoughts while doing the questions, starting from "Why does the teacher come up with this question?" What is he going to take? "Set out to find a solution.

Finally, calculation questions have always been a difficult part of chemistry exams. For the calculation questions, I still hope that the students can do more exercises, get in touch with various types of questions, and integrate the various problem-solving methods taught by the teacher. For those questions that you don't usually do, you should practice repeatedly and use the corresponding methods more.

Hopefully.

Chemistry, there are a lot of things to memorize, what are the properties of the substance, and the reactions that can occur, etc., I feel that you can find some elements that are commonly examined, and then make a systematic summary of their properties, physical properties, chemical properties, what things can react with, what things are generated, and what state these things are, what colors, and their structures, etc. In this way, finding connections with each other and forming a knowledge network will be of some benefit to you.

At that time, we were all codifying some biological knowledge into smooth words, and the key words were very practical and easy to remember.

Of course, there is a lot of biological knowledge that still needs to be understood, after all, it is science.

Ask the teacher, every teacher is familiar with their students, ask the teacher is right!

Both of them are very easy to learn, I'll tell you about chemistry, I didn't know this at first, a total of a few large pieces of knowledge, for example, organic is alkyrate, carefully get aside, this is almost over, piece by piece. It's good to get,.

There is no good way to do this! Summary! Get the knowledge framework right! Especially creatures! Be organized! Chemistry is miscellaneous! It's still up to memorization!

1 Ways to improve your high school chemistry scores in a short period of timeSimilar contrasts

In fact, after entering high school, many students can't find a way to learn, junior high school chemistry mastery knowledge is relatively less, high school chemistry knowledge needs to be mastered relatively more, junior high school chemistry in the classroom we can digest and understand, but high school chemistry needs us to consolidate our memory after class, chemistry in chemistry has a lot of chemical names and elements are very similar, which requires us to compare, Know what exactly is the difference between them.

Actively interact with the teacher in class

In the process of interacting with the teacher, we can avoid slipping in class and be able to concentrate, so that our listening efficiency will improve quickly, and we can ask the teacher if we don't understand any questions in class, so that our grades can improve quickly.

1 How can I improve my high school chemistry scoresChemical equations

In the process of learning chemistry, it is very necessary for us to master chemical equations if we want to improve our chemistry scores. In the chemistry test paper, the proportion of chemical equations in the remaining skin is very large, and there are many chemical equations that are often tested in the chemistry test paper, so we must pay attention to the chemical equations when we study chemistry.

Targeted questions

When we learn chemistry, we must do the questions in a targeted manner, not blindly, some students have done a lot of chemistry problems, but the grades still have not improved, so we must learn to do the questions, learn to find the questions, so that our vertical cavity difference chemistry scores can be improved.
