Junior high school chemistry is very poor, and finally I rushed for the middle school entrance examination for two months, and my grades were not bad.

1, I copied down all the chemical equations that appeared, and memorized all the troublesome scales.

2. Do more questions and write down all the missed questions.

3, textbooks, familiar with textbooks, familiar with textbooks, too sad, generally the following should be understood.

Chemistry in high school is not like this.

In high school, I found it impossible to learn like this. Unlike junior high school, which has four basic reactions and few equations. Many equations in high school are rare.

1, so I learned about redox for the first time and went to the square program every day.

2. Listen carefully in class and take notes. Chemistry is rather trivial. When reviewing in Grade Three, I found that my notes saved me a lot of time.

3, cultivate interest, cultivate a sense of accomplishment I have a great sense of accomplishment when I do the problem, and later I especially hope to meet what I can't, so that I can learn more. I like to look at the missing questions and remember some knowledge that is not in the textbook, which is equivalent to an expansion.

As a result, chemistry became my favorite subject. I hope I can help you, come on!
