Not bad, the topic of physical chemistry is a bit difficult, but there are also basic exercises in the book to consolidate what you learned that day, which is helpful to improve your grades. In fact, there is no difference between good and bad teaching AIDS, and using them well is the most important thing.

Canon in Canon is divided into three volumes: A, B and C. Volume A is the basic content, volume B is the consolidation and volume C is the improvement. Mathematics and physics, in particular, are difficult and challenging, which is very helpful for improvement. But there are not many questions, the key is to improve the ability and require a good grasp of the foundation.

Pay attention to the stage

Some reference books are suitable for synchronous learning in senior one and senior two, some are pre-examination review, and some are special breakthroughs or mock exams. For the students in Grade One and Grade Two, just learning a few knowledge points and not being proficient, they just bite the bullet and do simulation problems, which is equivalent to pulling out the seedlings to encourage them.

Mastering knowledge is a gradual and slow fermentation process. In this process, try to do as few questions as possible that are beyond your ability. The ideas and key points of each local proposition are different. As far as junior high school is concerned, there are even different learning versions. We must pay attention to this one.
